The reagent is highly selective and sensitive and it forms yellow coloured complex with mercury (II) having composition 1:2 (M:L) in alkaline pH range. Absorption of coloured complex in toluene is measured with reagent as blank at ƛmax 385 nm. The beers law is obeyed in concentration range from 0.5-5.8 ppm for mercury (II)Pyridine-2-carboxaldehyde 2-hydroxybenzoylhydrazone complex and it was evaluated from Ringboms plot. Molar absorptivity and Sandells sensitivity value for mercury (II)Pyridine-2-carboxaldehyde 2-hydroxybenzoylhydrazone complex are 5.87 ng cm -2 and 3.14 x 104 l mol -1 cm -1 , respectively. The sensitivity of the developed method was checked in presence of various foreign ions. The method is successfully applied for mercury (II) determination in binary, synthetic mixtures and real pharmaceutical samples. The accuracy and reliability of method was verified by AAS.","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77561745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, cellulose nanofibers were treated with acetic acid and acetic anhydride in presence of pyridine. The obtained cellulose fibers was characterized by Fourier Transformation Infrared Spectroscopy (FT-IR) and confirm the presence of OH, C-H bond and C-O-C groups in the synthesized Banana Peel Cellulose Nanofibers (BCNF) and presence of OH, C-H, C-O-C and CH3CO in the Acetylated Banana Peel Cellulose Nanofibers (Acetylated BCNF). The Size of BCNF and Acetylated BCNF were investigated by Field Emission Scanning Electron Microscope (FESEM) and Transmission Electron Microscopy (TEM). The synthesized BCNF and Acetylated BCNF investigated by FESEM and TEM was around 90 nm to 150 nm and 30 nm to 60 nm respectively. X-Ray Diffraction (XRD) Analysis was carried out for the BCNF and Acetylated BCNF. XRD result shows that synthesized BCNF and Acetylated BCNF were partially amorphous. The structural morphology was confirmed with the Atomic Force Microscopy (AFM). The Acetylated BCNF were successfully utilized in the preparation of membrane for water purification.","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86550176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The physico-chemical parameters were measured and water sampling were carried out monthly from June 2014 to May 2015 in eleven (11) sites well defined around Aghien lagoon. The parameters were determined using standard methods as defined by the French Association of Standardization (AFNOR). The Seasonal values of temperature, pH, turbidity, electrical conductivity, percentage dissolved oxygen and TSS in Water,falls to the following 26.31-29.76 °C; 6.95-8.03; 16.74-41.05 NTU; 63.15-109.11 μS/Cm; 63.91-100.21% and 8-31.18 mg/L respectively. ANOVA analysis result showed no significant differences (p>0.05) between seasons (dry and rainy) as for temperature, pH and electrical conductivity in all stations. For turbidity, dissolved oxygen and TSS, there was a significant difference between seasons. Seasonal concentrations of nutrient salts in water (mg/L) ranged from 0.01 to 0.14 for NO2 ; 0.48 and 1.93 for NO3 ; 0.06 and 1.90 for PO4 3. Seasonal variations showed a significant difference (p <0.05) for nitrate. The mean values of most parameters studied during both seasons are generally below the standard values recommended by the World Health Organization and SEQ Littoral. The calculated COD / BOD5 ratio showed that the water in the Aghien Lagoon is rich in biodegradable organic matter. The principal component analysis (P.C.A) of the data allowed to define three different types of water of the Aghien lagoon influenced by the seasonal variables. On the whole, the waters of the Aghien Lagoon could be used for the production of drinking water after treatment.","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75575902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
