Factorial Design Approach to Investigate the Effects of Groundwater Cooccurring Solutes on Arsenic Removal by Electrocoagulation
Publication: Journal of Hazardous, Toxic, and Radioactive Waste
Volume 15, Issue 1
Abstract
Effects of groundwater cooccurring solutes such as phosphate , silicate , bicarbonate , calcium (Ca), and iron (Fe) on arsenic removal were investigated in this study. Investigation by two-level full-factorial designed experiments revealed that and have negative effect on arsenic removal, whereas has negligible positive effect. The effects of Ca and Fe present in groundwater have positive effect on arsenic removal by electrocoagulation (EC). Hypothesis testing at 5% significance level suggests that alkalinity is not an important parameter in arsenic removal by EC in naturally occurring pH range of water.
