367672 Removal of Cadmium Ions from Aqueous Solution Using a New Low-Cost Biosorbent (original) (raw)

Abstract

In recent years, heavy metal pollution has increased as a result of industrial growth, especially in industries such as electroplating, mining, metal finishing, battery production, and welding. Among the heavy metals, one of the most hazardous is cadmium, which accumulates in the human body and causes cancer along with cardiovascular, neurological, and respiratory problems. Hence, it is crucial to sequester cadmium ions from industrial effluent before the contaminated effluent is discharged into the sewage system. There are several traditional treatment methods for removing heavy metals from aqueous effluents, including chemical precipitation, ion exchange, and membrane filtration. These techniques have high operational costs and require the continuous input of chemicals, so they are neither economical nor ecologically sustainable. Therefore, biosorption has gained significant attention as an effective alternative for sequestering toxic heavy metals. In this work, Sorghum X drummond...
