Absorbent from Cucurbita Pepo.L seed for Cu(II) removal

Abstract

Copper Cu (II) is one of the toxic contaminants of heavy metal in wastewater. The performance of activated carbon (AC) produced from Cucurbita Pepo.L seed as an adsorbent for the removal Cu is presented in this paper. The preparation of CPSAC uses 2-step physical activation assisted by microwave and CO2. The effect of contact time and initial concentration were examined. The batch study was conducted, and the data shows that the absorption was plotted better by using Langmuir isotherm.
