Ultrahigh energy He-Ag-Laser (224.3 nm) irradiations coupled with sonication were applied for the 1sttime as grains sizes splitter (promoter to lower sizes). The present investigations managed to introduce thermally-stable anatase TiO2 with ultrahigh BET surface area (789 m2g-1). Ti(IV)-tetra iso-propoxide (TTIP) was applied as precursor for synthesizing nano-TiO2. The produced gel (HO-Ti-O-Ti-O-Ti-OH)n was divided into two equal portions one as blank and other one forwarded to sonication/laser irradiations treatments by time dose equal to ~10 min. of laser irradiations per hour of sonication. Finally produced irradiated Gel dried in oven at 130°C followed by microwave assist to avoid any solvent tracer and finally sintered at 560°C for 4 h. The produced Ti(IV) oxide was carefully investigated and well characterized by Raman spectra, XRD, SEM and 3D-AFM.","PeriodicalId":13865,"journal":{"name":"international journal of chemical sciences","volume":"48 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86565637","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}

Nickel forms dark yellow colored complex, which can be quantitatively extracted in n-Butanol as solvent at pH 6.2. Beer’s law is obeyed in the range 3-50 μg giving a linear and reproducible graph under optimum conditions. The λmax is observed to be 395 nm. The complex obtained is studied by Job’s continuos variation method, mole ratio method and log-log method. The effect of pH as function of extraction, effect of solvents, effects of salting out agents, effect of reagent concentrations and interference study of foreign ions has been also studied. The molar absorptivity is found to be 0.4785 x 105 L mol-1 cm-1 and Sandell sensitivity is observed to be 0.0585 μg/cm2. The method developed is successfully applied to various commercial samples.","PeriodicalId":13865,"journal":{"name":"international journal of chemical sciences","volume":"57 1","pages":"391-398"},"PeriodicalIF":0.0,"publicationDate":"2014-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89385397","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}
