"Removal of Cu and pb ions from aqeous solutions by flotation method"


Abstract in English

In this search, the removal of copper and lead ions from aqeous solutions by flotation had been studied, and the effect of various factors on the removal process. The study showed that the removal of copper and lead ions was increased by increasing the value of the solution pH up to pH = 8 and the removal rate was 80%. At pH = 10 precipitation of the ions was obtained in the form of hydroxides. The removal ratio of both ions is increased by increasing the flow of the air within the solution to reach 98% for copper and 97% for lead at the flow of Q = 1000 ml/min and then the removal rate decreases to 60% with increasing airflow to Q = 1500 ml/min. The initial concentration values affect the removal process and the increase in the removal ratio was shown by increasing the initial concentration. The removal rate of copper ions was 50 % at the initial concentration of C0 = 50 mg / l to 98% at C0 = 100 mg / l. While the lead removal rate was 61 % at the initial Concentration C0 = 50 mg/l to 97% at concentration C0 = 100 mg / l.
