Abstract

This work is an attempt to remove Cr(VI) from simulated wastewater using electrocoagulation (EC) process where stainless steel (SS) is used as a sacrificial electrode. The central composite design (CCD) of response surface methodology (RSM) is used to optimize different operating parameters including initial pH (pHi: 1.5–9.5), current density (j: 20.75–104.15 A/m2), electrode gap (g: 1.5–2.5 cm), and treatment time (t: 0–30 min), with respect to the removal of Cr(VI) from simulated water. The high coefficient of determination for Cr(VI) (R2 = 0.9922) was found by the analysis of variance (ANOVA) between the experimental data and the predicted data using a second-order regression model. The maximum Cr(VI) removal of 88.9% was achieved at optimum conditions (pH 3.5, j = 83.3 A/m2, g = 1.75 cm, and t = 24 min) as reflected by ANOVA analysis. A foam and residues analysis has also been incorporated.

响应面法优化模拟水中电絮凝除铬工艺
本工作尝试使用不锈钢(SS)作为牺牲电极的电凝聚(EC)工艺从模拟废水中去除Cr(VI)。响应面法(RSM)的中心复合设计(CCD)用于优化不同的操作参数,包括初始pH(pHi:1.5–9.5)、电流密度(j:20.75–104.15 A/m2)、电极间隙(g:1.5–2.5 cm)和处理时间(t:0–30 min),以从模拟水中去除Cr(VI)。通过使用二阶回归模型对实验数据和预测数据之间的方差分析(ANOVA),发现Cr(VI)的高决定系数(R2=0.9922)。ANOVA分析显示,在最佳条件下(pH 3.5,j=83.3 A/m2,g=1.75 cm,t=24分钟),Cr(VI)的最大去除率为88.9%。还纳入了泡沫和残留物分析。
