Abstract

In this study, a ntural polymer, chitosan was modified with polyacrylamide (PAM) to prepare an efficient flocculant using redox grafting method. The effectiveness of the modified chitosan (chitosan grafted polyacrylamide) was tested on treatment of industrial textile wastewater. The effect of dosage, pH and settling time on the performance of flocculation process was also investigated. The treated textile wastewater was analyzed by its color removal, COD and turbidity reductions. The results obtained showed that the modified chitosan performed better than unmodified chitosan in the reduction of COD and turbidity of textile wastewater. Dalam kajian ini, polimer semulajadi, kitosan telah di modifikasikan dengan poliacrylamid (PAM) untuk menghasilkan flokulan yang efektif dengan menggunakan kaedah tergabung redox. Keberkesanan kitosan termodifikasi (kitosan tergabung polyacrylamid) telah di uji ke atas rawatan air sisa industri tekstil. Kesan dos, pH dan masa pemendapan ke atas keberkesanan proses flokulasi juga telah di kaji. Air sisa yang terawat di analisa untuk penyingkiran warna, pengurangan COD dan pengurangan kekeruhan. Keputusan yang diperolehi menunjukkan bahawa kitosan termodifikasi adalah lebih baik daripada kitosan tidak termodifikasi dalam pengurangan COD dan pengurangan kekeruhan sisa air tekstil.
