摘要：

The present study deals with the development of an innovative cost effective bentonite adsorbent coating (BAC) and simple mathematical equations are applied to enumerate coating requirement in treating textile effluent. The BAC has been successfully used for the removal of cationic dye from industrial wastewater. It has very good potential to be commercialized and applied by industries innovatively on the existing facilities with simple modifications. By installing bentonite coated fns inside tank, the concentration of dye can be easily reduced up to 90%. The BAC demonstrates good temperature and water resistant efficiency which can be easily coated on many surfaces. The best thickness and surface area of BAC for the optimal adsorption of dye (277.8 mg g(-1)) was found as 87 gm and 1.12 x 10(-2) m(2), respectively. The equilibrium adsorption data were best fitted by the Langmuir isotherm which indicates homogeneous monolayer adsorption. The mathematical formula obtained from isotherm model could be used in the removal and recovery of cationic dye (organic pollutant) in textile industry on large scale.
