Resumo
The influence of the internal phase nature and electrolyte solution on the electroflotation extraction of the low-soluble copper compounds from the PCB production flushing water of the electronic technology was specified. Electroflotation activity decreases in the series Cu(OH)2, CuCO3, Cu3PO4, CuS. The influence of the surfactants (SAT) on the kinetics of the electroflotation process, on the particle size of the internal phase and electrokinetic potential has been studied. The change in the ξ-potential (for anion and cation SAT) and particle size (1.5–2 times) was specified for SAT. The electroflotation efficiency of Cu(OH)2, Cu3PO4, and CuS under the optimum conditions is 98.5 and 90%, correspondingly.
