Existence of a very lesser quantity of dyes in water, which are still highly visible, extremely affects the quality and clearness of water bodies such as lakes, rivers, ponds and others water bodies, leading to harm to the aquatic environment. So it is significant to eliminate the harmful dyes which are very hazardous to the living organisms. Treatment of wastewater is challenging because dyes are water soluble so its removal becomes tough. In this work synthetic copolymer adsorbent of AA and AMP was successfully synthesized at many compositions. All the characteristic absorption bands of PAA and PAMP are observed by FTIR analysis, which indicates the successful copolymerization of AA and AMP. Adsorption experiments were accomplished at different contact time, adsorbent dose, pH conditions and temperature. 0.1 g dose of copolymer adsorbent has been found to be optimum for adsorption study. The kinetic study of adsorption was also investigated using pseudo first order kinetic model. From the study, it was establish that the prepared copolymer adsorbent was proficient to eliminate crystal violet dye at various temperature and time. Maximum 98% of crystal violet dye removal was achieved at high pH around 10. A maximum adsorption capacity of 9.8 mg/g was obtained for copolymer adsorbent of 1:1 ratio. Copolymer adsorbent (AA-AMP) provide a novel and effective type of adsorbents to remove CV dye from the aqueous solution. |
