Boron Removal from Mining and Synthetic Effluents by Electrocoagulation Using Aluminum Electrodes

Table 2

EC data to estimate the operational cost of synthetic effluent for 30, 60, 90, and 120 minutes using a current (i) of 3.0 A and supporting electrolyte (ES) of 0.200 mol L⁻¹, and for the mining effluent, for 90 minutes, using 3.0 A of current and 0.400 mol L⁻¹ of supporting electrolyte.

Effluent	Time (min)	Potential (V)	i (A)	Vol. (L)	ES (g)	CE (Wh L^−1)	ME (g)
Synthetic	30	12.6	3.0	4.0	68.00	4.725	0.503
Synthetic	60	12.5	3.0	4.0	68.00	9.375	1.006
Synthetic	90	11.7	3.0	4.0	68.00	13.162	1.510
Synthetic	120	12.8	3.0	4.0	68.00	19.200	2.013
Mining	90	3.5	3.0	4.0	29.80	3.937	1.510
