Study on Removal of Trivalent Chromium from Wastewater by Banana Peel

Abstract:

The toxic metals released into the aquatic environment though various industrial processes are detrimental to all living species. This paper used banana peels as an adsorbent for studying heavy metal Cr(III) containing in waste water. Respectively, the effects of the adsorption dosage, temperature, contact time, pH, initial Cr(III) ions concentration and shock time on adsorption were investigated. The results showed that under the following condition: the dosage was 0.1 g, the pH value of the wastewater was 2, the temperature is 30 °C, the shock time was 2 h, the initial mass concentration of Cr(III) was about 30 mg/L, the adsorbing capacity can be 22 mg/g. The adsorption reaction is an endothermic process and mainly physical adsorption. Using banana peels to treat chromium-contained wastewater has a very good application prospect.
