| Summary: | World water resources are polluted due to the release of many pollutants such as dyes, heavy metals, and others into water resources. Cadmium is a non-biodegradable heavy metal that has many toxicological effects on human health and is detrimental to the environment. Adsorption is the most widely used cadmium removal technique due to its effectiveness and simple operation. This study develops a kenaf-based magnetic biochar adsorbent for removing cadmium ions from model wastewater Raw kenaf fibers were firstly pre-treated with two techniques i.e. Chemical treatments (impregnation of kenaf fiber with sodium hydroxide), and thermal treatments (slow pyrolysis), before application in a batch system. Based on this, a synthesized magnetic biochar adsorbent was synthesized via a novel method using the precipitation of kenaf biochar with iron oxides (Fe3O4) and the sonication process. |
