ABSTRACT

Food waste residue poses a persistent global challenge. This research delves into the potential of utilizing adsorbents derived from food waste residue, referred to as AFWR, to extract heavy metals from food waste. The study successfully crafted low-cost adsorbents from tea waste and explored their capacity to remove stubborn compounds from synthetic wastewater. Moreover, the study applied response surface methodology to examine the interactive influence of key parameters: adsorbent dosage, initial concentration, solution pH, and adsorbent quantity.

Tea waste emerges as a cost-effective and efficient adsorbent for eliminating copper ions from wastewater. Experimental findings revealed that under optimal conditions (pH 5, 120 minutes of contact time, 1g of adsorbent per 200ml, and a 10ppm concentration), tea waste achieved an impressive 95.98% removal of copper ions. These experiments on adsorbents hold significant promise for the development of suitable technologies aimed at purging heavy metal ions from polluted industrial effluents.
