UPTAKE OF DYES FROM AQUEOUS SOLUTION BY USING OPERCULINA TURPETHUM-A BIOMATERIAL

Abstract

A carbonaceous sorbent prepared from an indigenous agricultural waste Opercuuna turpethum (Convolvulaceae), by acid treatment was tested for its efficiency in removing basic dyes (Auramine-O, Methylene Blue and Rhodamine B) from aqueous solution . Preliminary studies have shown that the removal was faster with less time and less adsorbent dose required for maximum removal. Thermodynamic parameters obtained from the temperatures studies revealed that uptake process is endothermic and spontaneous.
