Abstract

Abstract: PS(polystyrene) and EC(ethyl cellulose) were dissolved with CH₂Cl₂, and PS-ECmicrocapsule was prepared by means of drying in water.When the tiny pores of the film contain TBP(tributyl phosphate), it shows the function transferring.Cr₂O₇^2- We investigated the effect of proportions of PSand EC, the radii of microcapsule, and the concentrations of NaOHand TBP.The results show that the concentration of was dropped down in l0min from 1×10^-4 mol/Lto 1×10^-7mol/Lunder the appropriate conditions.

Key words: Microcapsule, Polystyrene, Ethyl cellulose.Transfer of chromium ion
