Abstract
Tannery effluent is a major challenge in wastewater management because it contains a lot of chromium (VI); which has deleterious impacts thus remediation treatment is therefore necessary. This study  used waste agriculture materials as banana peels to removal hexavalent chromium. Banana peels were used as adsorbent materials in  normal form and nanoparticles. Characterization of normal and nano size of banana peel by  transmission electron microscopy (TEM) and FT-IR spectroscopy were evaluated Adsorption experiments were performed on the standard aqueous solutions of Cr (VI) and tannery effluent for varying adsorbent doses; contact times; pH; and concentration of metal. The residual chromium (VI) was determined using the  (Inductively Coupled Plasma)  . The Langmuir isotherm's model fits the adsorption data perfectly. The nano powder of banana peels eliminated 98.95% of the residue; compared to the conventional powder of banana peels; which removed up to 72.45%. It has been observed that by using nanometric banana peels; the adsorption efficiency can be increased0 in a shorter time compared to peels normal size The isotherm model from Langmuir and the data on adsorption are strongly associated. The results demonstrated that banana peel nanoparticles were effective at chromium adsorption from effluent from tanneries; reaching 95% at 120 minutes; pH 4; and weight eight grams.
