- Abstract:
- In this paper , the high purity liquid reactive black was prepared by using the membrane separationtechnology ,including the microfiltration(MF) membrane for removing particulate，the Charged-mosiac ,mem-brane(CMM) for desalination in the constant-volume filtration and the nanofiltration(NF) membrane for dehy-dration.The solid reactive black with high purity was prepared by spray drying.The experimental results showthat with the 61.5 g ·L ’ raw material liquid，under the pressure of 1.0 MPa, the salts were removed after 8hours desalination.The purity of dye could meet the requirement and the loss rate of the dye was 0.62% . Theaverage permeation flux of the charged-mosiac membrane was 18.5 L· m .h-’ during the desalinationprocess,which illustrated that the fouling of membrane was not so serious. Under the pressure of 1.4-1.8MPa , the reactive black concentration can achieve 250 g·L ’ by dehydration. The solid dye was prepared bythe spray drying.It was analysed that the inorganic salt in the product was lower than the imported productused by the enterprise. To sum up, the product prepared in the experiment has a good application prospect.
