چکیده
|
In this study cost effective remediation of tannery effluent was performed by alkaline treatment followed by filtration over neem leaves powder. the effluent was contaminated by deep blue color, distasteful odor, slightly basic ph, tds, ec, cod, cr and cu. the color, tds, ec and cod were declined in a mentionable trend by alkali treatment in different ph, however, the concentration of cr and cu was unaffected. after filtration of alkali treated tannery effluent over azadirachta indica powder, showed highly satisfactory removal efficiency for cr and cu. the removal efficiency of cr and cu ions over azadirachta indica was 97 and 98 %, respectively.
