The Diminution of Toxic Ions by using Mangifera Indica Foliages as Adsorption from Textile Effluent

Abstract

Mangifera indica leaf powder (MIFP) was used as a non-conventional plant biosorbent developed from mature leaves of mango, was investigated in batch adsorption experiments on textile wastewater. Process parameter which includes pH, adsorbent dosages and contact time were varied in order to evaluate their influence on the adsorption process. As the Mangifera indica foliages are locally available easily and are also cost-effective, so it can be used in little greater amounts to obtain complete removal of heavy metals. The percentage removal efficiency of Cu(II) was higher with increasing contact time and the equipoise time in nearly 240 minutes as 89.94 at pH 7 in the dosage content of 2.0g. The percentage removal efficiency of Cd(II) and Pb(II) were attained in contact time of 180 minutes such as 89.61 and 84.42, with the level of pH 6 respectively, and Zn (II) was 85.88 and Ni(II) was 89.94, at pH 7 severally. The results obtained indicated that the adsorption of Ni(II) on MIFP was better than other ions. Besides that, the adsorption of Ni on MIFP was found in the good fit with the Langmuir isotherm.
