Removal of chromium with CNT coated activated carbon for waste water treatment

In this study, removal of chromium was accomplished by using carbon nanotubes from aqueous solution, with the optimization of process variables including the dose of initial pH, agitation speed, adsorbent, initial chromium concentration and contact time. The run orders for complete randomized experi...
