Removal of (Acid Red 18) dye from aqueous solution using an poly (DEAEMA-CO-HEMA) absorbent

One of the hazardous waste waters is the textile industrial dye containing waste waters. Purification of wastewater from dye due to hazardous properties and their impact on the environment is very important. Azo dyes are the largest and prominent type of dyes. They have one or more Azo (N=N) groups between one or more aromatic rings. In this study we considered removal of anionic Acid red (Acid Red 18) (AR18) with the use of poly (DEAEMA-CO-HEMA) absorbent. In this study we examined the impact of some parameters like, time of collision, absorbent material's amount, initial dye concentration, rate of mixing, and PH. Optimum amounts of absorbent was 0.04gr and maximum of removal accrued to pH=5 and 25C0 temperature. In this examination the kinetic of one and two degrees and the isotherm of Langmuir and Freundlich Was examined and showed that it has followed from two isotherms. The result show that with increasing the time of collision the efficiency of dye removal was also increased but with increasing the PH of solution and initial dye concentration dye removal was decreased. The corresponded analyses determined with SEM, TGA, FTIR and DSC.
