Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - In the present study biosorption method was used which was quite effective and economical. For this purpose corn cob powder (Zea maize) waste of very popular food crop in Asia was used as biosorbent. The efficiency of Corn Cob for the remediation of Chromium (VI) was studied by varying parameters: pH, temperature, contact time, biosorbent concentration with specified ranges mentioned on experimental work design. It was observed that percentage removal of Cr (VI) from its aqueous solution increased when pH and biosorbent concentration increased and temperature and contact time decreased. Test solutions of known concentration of Cr (VI) were prepared. Percentage reduction was calculated for each experiment. Analysis of Variance was applied to know the significance of certain variables. Values 0.05 were significant. Maximum percentage reduction of Cr (VI) was 98.64.…

The basic purpose of this study is to evaluate low cost adsorbent for dye removal. Being carcinogen Congo red is hazardous and toxic. Batch wise removal were executed in order to estimate the effects of a various experimental parameters like Mesh size, adsorbent dose, contact time, temperature, agitation speed and pH. Adsorbent was treated with 0.1M HCl and 0.1M NaOH. Similar experimental parameters were performed for these acid and base treated adsorbents. Comparative study revealed that acid treated is the adsorbent. However, pH factor showed maximum percentage of adsorption in U.T.B. Langmuir and Freundlich Isothermal model were used to explain the equilibrium for these adsorption processes. Study revealed that adsorption followed Langmuir model for A.T.B and B.T.B whereas freundlich model for U.T.B. The adsorption capacity was 0.06, 0.24 and 0.12 mg/g for untreated, acid and base treated respectively. The maximum capacity observed for A.T.B in Langmuir isotherm. So, acid treated Raphanus Sativus peel are potential adsorbents for Congo red removal.…
