Abstract
The processes of heavy metals extraction from dilute solutions using the reverse osmosis membrane Filmtec TW 30-1812-50 were studied. It was shown when the copper sulfate solution was filtered with copper concentration from 2 μkg/dm3 to 5 mg/dm3, it was possible to achieve its full extraction. The dependence of the membrane productivity on the degree of permiatе selection was established. The membrane selectivity for zinc and nickel ions amounted to 60.51 to 80.74% and 71 to 95%, respectively. With the use of complexone, it was possible to achieve an effective recovery of cadmium, the membrane selectivity was 91–95%. This technique can be used in concentrating samples for the analysis of cadmium content in water.
