Because of their poisonous nature and inability to biodegrade, heavy metals have developed into a significant water pollution problem. Banana peel was created as a bioadsorbent in this study to filter out heavy metals from tainted water. The primary issue with banana peel bioadsorbent is that, in comparison to its commercial equivalent, activated carbon made from biomass sources has negligible adsorption capacity. In addition, a substantial amount of banana peel wastes adds to the challenge of disposal.Thus, by transforming banana peels into bioadsorbent, the current effort is anticipated to address the issues associated with banana peel disposal. The creation of a bioadsorbent made from banana peels and an evaluation of its effectiveness in adsorbing heavy metals are the goals of this study. We also used various parameters for test of Ni removal ability of bio-adsorbent like including optimizing of pH, temperature of solution, dosage of adsorbent, contact time and solid-liquid ratio.The extensive use of inexpensive raw materials as bioadsorbent in wastewater operations is strongly advised due to their simple processing, widespread availability, and environmental friendliness.
