Breakthrough curves of synthetic and real acidic copper-plating wastewater on a Dowex 50X8 strongly acidic cation exchanger. Solution pH : 1.0; Cu(II) concentration: 400 ppm; amount of resin: 4 g; throughput rate: 2.6 mL/min. C/C o represents concentration of Cu in the effluent to that in the influent solution.

... the recovery of Cu(II) from synthetic, acidic, copper-plating wastewa- ter with strongly acidic, Dowex 50X8 resin, 1 L of 400 ppm Cu(II) solution adjusted to pH 1 was passed through a 4 g resin column at 2.6 mL/min. The capacity of the resin was saturated after the flow of 950 mL Cu(II) solution. (See Fig. 1.) The retained copper was eluted with 75 mL of 1 M H 2 SO 4 , and the resin breakthrough capacity was found as mg Cu/g resin. An acidic copper-plating wastewater sample containing 400 ppm Cu(II) was run simultaneously (Fig. ...
