Characterization and application of activated carbon prepared from waste coir pith

Abstract

Activated carbon (AC) has been prepared from raw coconut pith and coconut pith impregnated with H 3 PO 4 and NaOH solutions separately. AC was characterized with SEM, particle size analyzer and proximate analyzer. Adsorption studies were carried out using UV and atomic absorption spectrophotometer to find its effectiveness. AC obtained from coconut pith treated with phosphoric acid was found comparable to the commercial grade samples.
