Adsorption Properties Of X-Type Cationic Dyes

    The adsorption and desorption properties of cation exchange membranes under different conditions were studied by adsorption and adsorption kinetics of cationic red X-gtl. Results show that the adsorption process mainly occurs in the first 20min, accords with pseudo two-level kinetic model, and the adsorption process can be described better by using Langmuir adsorption model; the Nas0 of inorganic salts in dye solution has certain influence on adsorption, and desorption rate can reach more than 94% by using anhydrous ethanol and sodium chloride aqueous solution. The cation exchange membrane has good repeatability.X-Type Cationic Dyes

    With the increasingly stringent wastewater discharge standards and rising water charges, people urge the development of sewage resources technology, and gradually focus on dye-containing wastewater in depth treatment and reuse. Ion exchange membrane is a kind of polymer functional membrane or separation membrane with selective permeation, which uses the selective permeation of ion exchange groups, so it is also called ion selective permeation membrane. The ion exchange membrane has the advantages of high separation efficiency, low energy consumption and less pollution, so it has important application value in many aspects.X-Type Cationic Dyes

    Material cation exchange membrane (UK Whatman company), cationic red X. GTL, hydrochloric acid, sodium hydroxide, sodium sulfate, sodium chloride, potassium chloride, potassium thiocyanate, methanol, anhydrous ethanol (all analytical pure), UV-vis spectrophotometer, in a certain wavelength range of different concentrations (8, L2, L6, 2O, 24mg/l) The absorption of cationic red x-gtl dye solution, Determine the maximum absorption wavelength of 494nm and draw the standard curve.X-Type Cationic Dyes
