Rugao Xingwu Chemical Co.,Ltd | Updated: Dec 16, 2016

Adsorption is the use of porous solids in contact with wastewater, using adsorbent surface activity of dye wastewater by Organics and metal ions adsorption and concentration on its surface, the purpose of purifying the water. Structure, properties of adsorbent and adsorption conditions can affect the adsorption effect. Adsorbents are activated carbon, resins, minerals, waste and the new adsorption material, adsorbents, are strong adsorption capacity, regeneration or recycling, source in the direction of wide, low prices.

By macroporous resin adsorption process of naphthalene dye intermediate wastewater not only high adsorption efficiency, good effect, and can reclaim valuable raw materials and intermediates from the wastewater, is a practical measure that has a good prospect. Duggan determined through experiments such as Orna, lignite with 50% sodium tungstate solution treatment, carbonization at 800 ℃, can greatly improve the effect of brown coal on the adsorption of acid dyes. Study of ACIDized palygorskite clay on the cationic dye (pink FG, concentration was 500mg/L) adsorption performance, found that when 2400mg/L is adsorbent addition concentration, dye adsorption rate of 92%. Simulation of cationic dye Crystal Violet solution water study of dye adsorption performance of slag and its influencing factors. Results indicate that under alkaline conditions, slag adsorption of Crystal Violet is not only fast and high adsorption capacity. PAF with potato residue fiber with cationic dyes wastewater by adsorption of, research results show that, in the experimental range, PAF on the static adsorption of cationic red x-11.10mg/g. New eco-MnO2 using cationic dye wastewater treatment research of cationic dyes wastewater by finding new eco-MnO2 has good effect and high adsorption decolorization, COD removal rate of up to 99% and 95%, respectively.
