تقدير افضل دالة حامضية لازالة النيكل من الترب الملوثة باستخدام الطريقة الكهروحركية

Abstract

The aim of this laboratory study is to estimate the best initial pH of purging solution for Nikel clean-up from artificially contaminated soil using electro-kinetic cells. An efficiency enhancement method was employed involving pH control and injection wells as part of the investigative program. Seven tests were performed at different pH-controlled in anode; cathode and injection wells start from 2 to 8. Sandy loam soil was contaminated with Nikel concentration equal to 2000 mg/kg and initial moisture content equal to 30%. The duration of remediation was seven days with a potential gradient of 1.2 V/cm. The experimental results showed that the best removal efficiency is 64.7% were achieved in pH equal to 3.
