Mercury Removal Using Fe –Fe Electrodes by Electrocoagulation
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 1
Abstract
ABSTRACT: The performance of electrocoagulation is a promising electrochemical technique with iron scarified anode for waste water treatment on laboratory scale was done. Several parameters like initial metal concentration, pH, voltage, agitation and electrolyte concentration at different time were investigated to achieve a higher removal rate of mercury. Experiments were carried out with different initial metal concentration ranging from 30 ppm , 50 ppm and 100 ppm, pH ranging from 2.5 pH, 4.5 pH and 7.0 pH, Voltage vary from 6V, 9V and 12V, electrolyte concentration changes from 0.6667 g/lit., 1.333 g/lit. and 2.0 g/lit., agitation vary from 200 rpm, 400 rpm and 600 rpm with a constant spacing between two electrodes is 1.0 cm. Maximum mercury removal was achieved at the end of 40 minute operation. Total operating cost also calculated from the power cost and cost of electrode material. The method was found to be highly efficient and relatively fast compared to conventional existing techniques.
