摘要

In this paper, the feasibility of using a low-cost agricultural waste, Ziziphus nummularia kernel, for the removal of erythrosine toxin color from wastewater that causes inflicts irreparable damage on environmental cycle and human health was investigated. Erythrosine is known as severely pollutant to the aquatic environment. Ziziphus nummularia kernel had no significant application; it was suggested that the Ziziphus nummularia kernel to be used as a natural adsorbent of erythrosine dyes. From the experimental data, the low cost natural adsorption material responded very efficient for the removal of dye. It this work, the effect of pH, contact time, dye concentration, temperature and the amount of adsorbent for the rate of bleaching of the dye were investigated. Application of adsorption models, Langmuir and Freundlich adsorption isotherms were evaluated. The adsorption process was in good agreement with Langmuir adsorption isotherm. Result of bleaching erythrosine dyes with concentration of 20 mg L 1 on Ziziphus nummularia kernel sorbent with concentration of 0.1 g L 1 showed 93.7% of dye efficiently removed. The adsorbent capacity 101 mmol of dye g 1 of adsorbent was achieved.
