Comparative Studies of Selected Physicochemical Parameters of Functionalized KOH-CSAC with other Sustainable Agrowaste-Based Materials

Abstract

Effectiveness of material is dependent on the quality physicochemical properties required for the suitability and sustainable applicability. In this study, potassium hydroxide functionalized coconut shell activated carbon (KOH-CSAC) was developed and the unique physicochemical properties; point of zero charge, pH(PZC); Ash content; %moisture content; bulk-density; %carbon content and Sear’s surface area were determined. The pHPZC was 7.10, the moisture content obtained was 10.3%, the bulk density was 0.7232, the ash content and carbon content were 0.1% and 70.105% respectively. The Sear’s surface area of 42.2 m2/g obtained superseded previously reported sustainable material as compared. The data obtained revealed better physicochemical properties as compared to other activated carbon. KOH-CSAC can favourably compete with the commercial activated carbon. The developed functionalized KOH-CSAC could function as a promising low-cost and sustainable material that could find application in remediation of the environment to provide safer and clean environment in actualization of Sustainable Development Goal 6 of Clean Water and Sanitation.
