orange crystals are obtained. These are dissolved in 17 ml of dioxane at the boiling point, 0.6 g of active charcoal is added to the solution and the solution is then filtered hot. The filtrate is cooled and 40 ml of diethyl ether are added. The colourless crystals which have precipitated...
This study aims to find a sustainable solution for dye removal by investigating the potential of an indigenously isolated bacterium, Nesterenkonia lacusekhoensis EMLA3 (halo-alkaliphilic) for treatment of an azo dye, methyl orange (MO) and textile effluent. MO dye decolorization studies were ...
In this work, alkali treated wheat straw (ATWS) materials were simply modified by triethoxysilylpropylamine (TESPA) to prepare a novel adsorbent. The adsorption of methyl orange (MO) from aqueous solutions onto the modified wheat straw was studied. The adsorbent was characterized by scanning ...
