Removal of Lead from Industrial Water Using Natural Adsorbents

Abstract

Due to their acute toxicity and accumulation in food chains, water contamination by heavy metals such as lead, arsenic, mercury, aluminum, zinc, chromium, and iron is a significant environmental problem.Lead is one of these highly toxic heavy metals that can occur naturally or be manufactured in industries such as storage batteries, radiators, and joint solder.As a result, this research examined the feasibility of using low-cost adsorbents to remove lead from contaminated water.Thus, our study aims to investigate the ability of natural bio sorbents for removing very toxic Pb 2+ ions from an aqueous solution.Contact time, concentration, adsorbent-based dosage, and pH are evaluated as important factors in the adsorption mechanism.The adsorption efficiency discovered was pH reliant, rising as the pH of the solution to some ranges of 2.5 -6.5.After 120 minutes, stability is attained, and the optimum removal rate was obtained with a 1.5-gram adsorbent loaded weight.
