The characterization study involves measurement of apparent density, swelling, mechanical strength and microstructure. The PVA added SPH are treated for a total time of 550 minutes in double distilled water and acid salt solution to analyse the swelling properties. The result shows that inclusion of PVA to SPH reduces its swelling tendency culminating that; the empathy for swelling is more in double distilled water than acid medium.","PeriodicalId":7399,"journal":{"name":"American Chemical Science Journal","volume":"33 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89277044","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 delignification ability of the ethanol-alkali organosolv system was somewhat better than the caustic soda system. However, the ethanol addition into the caustic soda reflux system improved yield with probably carbohydrate retention in the pulp. Moreover, bio-treatment of jute prior to ethanol-alkali pulping under reflux system does not affect the delignification and yield. The maximum burst and tensile strength for ethanol-alkali system was found to be at 1 h. Cooking time with 3.9 kPa m 2 /g and 66.1 N m/g, respectively. However, increasing the reflux time for beyond 1 hour markedly reduce strengths. Moreover, the tear strengths of jute pulps from the caustic soda system were higher than pulps from the both untreated and bio-treated ethanol-alkali systems. The highest tear strength of 22.5 mN m 2 /g was also found with 1 h. Cooking in caustic soda system.","PeriodicalId":7399,"journal":{"name":"American Chemical Science Journal","volume":"53 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89139164","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 surface morphology of fabricated Nano composites cadmium oxide was analyzed by Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microcopy (SEM) techniques. The treatment of simulated dyes wastewater was carried out by adsorption method using CdO Nano composites. In addition Malachite Green Oxalate (MGO) was selected as a model replicated system of dye wastewater, to explore the potential practicability for the elimination of the toxic dye. The adsorption experiments were heralded under the optimized conditions like adsorbent dosage, dye concentration and temperature. The acceptability of adsorption progression was estimated by proceeding adsorption models like Freundlich, Langmuir and D-R (Dubinin–Radushkevich). The values of R 2 show that Freundlich model is the best fitted model. The thermodynamic study was conducted to determine the values of free energy (∆G°), entropy (∆S°) and enthalpy (∆H°) change of the system. Adsorption Kinetic was also studied by Boyd’s model. The results demonstrated that adsorption efficiency was found to be 93% for Cadmium Oxidedye-Nano composites systems. The present model system can be employed on industrial scale as a single step process for the removal of dye pollutants and thus it could provide a new raised area for waste minimization.
