The equilibrium adsorption data were analyzed using adsorption models of Langmuir, Freundlich and Temkin. The thermodynamic and kinetics parameters were calculated using adsorption process on nano ZnO for the methylene blue solution at different temperatures. It was found that a ZnO at nano level has a very significant adsorption for methylene blue compared to that of raw materials. The results showed that the model isotherms are fitting very well with the experimental data. The specific adsorption percentage of methylene blue was highly affected by addition of nano ZnO and decreasing with temperature compared to that of control sample. It has been found that the adsorption capacity was increased by increasing the methylene blue concentrations, and these values indicated that the methylene blue adsorption onto nano ZnO was spontaneous and endothermic in nature. All values of Gibbs functions were negative with values of -15 and -17 kJmol -1 for temperatures of 293 to 323K, while values of enthalpy and entropy about -33 kJmol -1","PeriodicalId":7399,"journal":{"name":"American Chemical Science Journal","volume":"35 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74015182","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 temperature varied between 480 and 520°C. The biomass (moisture of 10%) was fed with a rate between 20 and 35 kg/h. Approximately 4.5 kg of sand was used as fluidizing agent. The pyrolytic oil was analyzed for the contents of carbon, hydrogen and nitrogen and sulfur. Water content, acidity, pH, viscosity at 40°C, density and higher heating value were also determined. Chromatographic analysis showed that it was composed mostly of acetic acid, syringol, vinyl-phenol, guaiacol and hexanoic acid. Main results are used to compare the influence of different configurations of a gas-washing column and vapor condensation system on the properties of the bio-oil.

Material and Method: The various compounds in the n-hexane extract of the leaf were analysed by TLC and identified by GC-MS technique. The TLC results indicated that four (4) terpenes are present in hexane extracts of the leaf of Syzygium guineense after treating TLC plates with vanillin-Conc.H2SO4. Results: The results of the GC-MS analysis revealed twelve (12) compounds in the n-hexane extract of Syzygium guineense leaf.
