摘要: Abstract In this paper, we proposed a simple, rapid and continuous method of solvent extraction for hexavalent chromium from aqueous solution in high gradient magnetic separator. We constructed the theoretical modeling introduced original so-called “magnetic extractant”. The feasibility using was verified by experiments. static force analysis balance extractant separator were studied. efficiency porosity related to accumulation radius. By mathematical derivation, radius determined susceptibilities extractant, intensity background field wire influences designs ferromagnetic filler separator, types diluent, pH values Cr (VI) feed solution, concentration, flow rate, temperature investigated. results showed that increased with decrease value rate increase TBP concentration temperature. Under optimum conditions, obtained capacity process 6 h 1800 ml solution.
