The method involved the oxidimetric treatment of atenolol and propanolol with 2 x 10-3 mol L-1 KMnO4 in alkaline medium (pH ≥ 9). Scanned spectra of oxidized complex showed distinctive absorptions at 460, 520, 540 and 570 nm. Arrays of colour changes were observed - from violet to blue; blue to bluish-green and yellow. Exhibited colours were due to ligand-metal charge transfer. An indirect spectrophotometric determination of atenolol and propranolol was done after 12-15 minutes at 520 nm. The optimum assay conditions showed linearity ranged from 0 – 15.0 μg mL-1 for both beta-blockers (R= 0.9997 – 0.9999). Molar absorptivity values were 4.79 x 103 and 4.88 x 103 L mol-1 cm-1 for atenolol and propanolol respectively, with corresponding Sandell’s sensitivity values of 0.056 and 0.053 μg cm-2. Limits of detection and quantification were 0.50 and 1.65 μg mL-1 for atenolol respectively and 0.58 and 1.91 μg mL-1 for propanolol, while relative standard deviation for intra-and inter-day precision were < 2.0%. The applicability, accuracy and reliability of the method were demonstrated by the determination of atenolol and propanolol in tablet formulations. The recovery studies ranged from 93.33 - 103.00% for both beta-blockers and the amounts in brands were from 97.53 ± 2.68 to 100.84 ± 1.82%.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"109 1","pages":"56 - 64"},"PeriodicalIF":4.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78854410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological monitoring plays an important role in exposure assessment of workers occupationally exposed to chemicals. Several metabolites have been proposed for biological monitoring of individuals who are exposed to BTEX. There are a variety of extraction methods and analytical techniques for the determination of unmetabolized BTEX in exhaled air and their urinary metabolites. The present study aimed to summarize and review the toxicokinetics of BTEX and sample preparation and analytical methods for their measurement. Metabolites of BTEX are discussed to find out reliable ones for biological monitoring of workers exposed to these chemicals. In addition, analytical methods for unmetabolized BTEX in exhaled air and their metabolites were reviewed in order to obtain a comparison between them in term of selectivity, sensitivity, simplicity, time, environmental-friendly and cost. Given the recent trends in sample preparation, including miniaturization, automation, high-throughput performance, and on-line coupling with analytical instrument, it seems that microextraction techniques, especially microextraction by packed sorbents are the methods of choice for the determination of the BTEX metabolites.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"54 1","pages":"168 - 187"},"PeriodicalIF":4.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89349893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But unclear labelling and false information of animal origin of gelatin in those products would violate religious rules and increase public health risks. Recently, animal origin identification of gelatin-based products has drawn more and more concerns. Among various identification methods, liquid chromatography-mass spectrometry (LC-MS) has specifically become a research hotspot for animal origin identification and quantitative analysis of gelatin-based products due to its superior reliability, selectivity, and sensitivity. The main desideratum of the current treatise is to review the recent progress on this subject with respect to: (1) the identification of animal in halal gelatin-based products, (2) the determination of the authenticity of gelatinous medicines from animal, especially from the highly homologous family species, and (3) the quantification of gelatin in gelatin-based products, using LC-MS method. We hope that this review could provide theoretical guidance and advanced strategies for developing animal origin identification technologies for gelatin-based products.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"6 1","pages":"260 - 271"},"PeriodicalIF":4.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82510578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sensitive and robust interface is essential in CE-ESI-MS. Continued development of CE-ESI-MS interfaces in the last decade, including junction-at-the-tip interfaces and sheathless interfaces, has improved the sensitivity and robustness of CE-ESI-MS significantly. The limited loading capacity of CE, one of major reasons that limits the utility of CE as a routine separation method, has also been addressed effectively by the use of in-capillary sample preconcentration techniques, such as transient CITP/CZE and dynamic pH junction. CE-ESI-MS could yield higher sensitivity as compared with the conventional LC-ESI-MS, and, therefore, is capable of identifying more proteins and peptides when the sample amount is very limited, such as single cell analysis. To improve the protein sequence coverage, CE-ESI-MS can also be used as a complementary technique to LC-ESI-MS, or combined with reversed phase LC to form a two dimensional separation technique. CE-ESI-MS is also effective in quantifying targeted peptides/proteins in complex bio-matrix.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"11 1","pages":"45 - 55"},"PeriodicalIF":4.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79518812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These compounds have been of concern as carcinogens and mutagens for the past 50-60 years. Lately, they are also receiving attention as endocrine-disrupting chemicals. Therefore, proper analytical methods are required for sampling and analyzing these compounds. In response to problems associated with the conventional methods like solid-phase extraction (SPE) and liquid-liquid extraction (LLE), many studies have focused on the miniaturization of different sample preparation techniques. In this regard, the use of different types of liquid phase microextraction (LPME) techniques has increased significantly during the recent few decades. LPME techniques are advantageous because they use single-step sample preparation and have shown a greater sensitivity, selectivity, and efficiency than the conventional methods. In addition, these techniques have good potential for automation, to reduce the time and cost of analysis. This review focuses on the most important configurations of LPME including single‐drop microextraction (SDME), hollow-fiber liquid-phase microextraction (HF-LPME), and dispersive liquid-liquid microextraction (DLLME) techniques used for the sampling and determination of PAHs in different samples, along with their cons and pros, as well as their prospects.","PeriodicalId":21090,"journal":{"name":"Reviews in Analytical Chemistry","volume":"43 1","pages":"1 - 19"},"PeriodicalIF":4.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90751312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
