Removal of Cationic Dyes by Polyphenylene Sulfide-based Strong Acid Ion Exchange Fiber
PPS-based strong acid ion exchange fiber was used to absorb cationic dye basic fuchsin and methyl blue in solution.The experimental results showed that the amount of methylene blue and basic fuchsin absorbed increased respectively with increasing of initial concentration from 100 to 600 mg/L.The adsorption capacity of the fiber was up to 604.81mg/g of basic fuchsin and to 618.94mg/g of methylene blue.The removal rate of the methylene blue reached 99.9% from 100 to 500mg/L,but of basic fuchsin from 100 to 300mg/L.Adsorption kinetic equation for basic fuchsin can be expressed as a pseudo-second-order dynamic process.The fiber is to be perfect prospect for the wastewater treatment because of its high adsorptive capacity and diffusion rate.
