The indiscriminate discharge of heavy metals into wastewater and soil as a result of human industrial practises is posing a severe hazard to the environment. Heavy metals in the environment have been a major source of worry in recent years due to their toxicity, bioaccumulation potential, and hazard to human life and the ecosystem. Hexavalent chromium metal is a carcinogenic pollutant that may be found in industrial effluent from a number of sources. As a result, chromium reduction and recovery from tannery effluent is critical for both environmental and economic reasons. The major goal of this research is to improve a novel composite for polluted water depollution. This paper describes the characterisation and use of chitosan-coated activated carbon derived from Ziziphus mauritiana bark as a potential adsorbent for the removal of Cr(VI) from aqueous solution. SEM analysis revealed the mesoporous nature of the material under investigation. The batch experiment was carried out to investigate how essential process variables such as pH, contact duration, adsorbent doses, and the baseline Cr(VI) concentration influenced the outcomes. The maximum adsorption effectiveness for Cr(VI) removal by CCZMAC was observed at pH 4.5, 5 gm/lit adsorbent dose, and 140 min contact time. Under optimum conditions, 97 percent of Cr(VI) was removed from aqueous solution. This research demonstrates that CCZMAC, a mesoporous material, may be employed as an excellent sorbent material for extracting Cr(VI) from polluted water and can therefore be used in wastewater treatment.
