Abstract

Kajian ini melibatkan tiga peringkat yang berbeza iaitu pembuku-bio yang diekstrak daripada batang pisang dan jerami padi, rawatan efluen terawat air sisa tekstil menggunakan menggunakan ekstrak pembuku-bio dan ujian toksik keatas enapcemar yang terhasil selepas proses pengentalan dan pemberbukuan. Pembuku-bio yang diekstrak daripada batang pisang menggunakan proses ekstrak asid panas didapati lebih tinggi hasilnya iaitu 32.8% sementara hanya 16.2% daripada jerami padi yang berjaya dikumpul daripada berat asal masing-masing (10g). Seterusnya, pembuku-bio dianalisa menggunakan spektoskopi FTIR untuk mengenal pasti kehadiran kumpulan berfungsi yang membantu dalam proses pemberbukuan. Kumpulan hidroksil dan karboksil telah dikenalpasti hadir di dalam analisis FTIR. Efluen terawat air sisa tekstil di analisa bagi pengurangan warna dan keperluan oksigen kimia (COD) menggunakan ujian kelalang oleh pengental (FeCl3) dan pemberbukuan ( P dan PAM). This study involve three different stages which are extraction of bio-flocculant (P) from banana pseudo-stem and rice straw, treatment of textile wastewater treated effluent using extracted bio-flocculant and phytotoxicity test on the sludge produced after coagulation and flocculation process. The bio-flocculant extracted from banana pseudo-stem using hot acid extraction process was found to be higher in yield at 32.8 % while only 16.2% from rice straw was manage to collect from the dry weight 10 g respectively. Later the bio-flocculant was analysing using Fourier Transform Infrared Spectroscopy (FTIR) to detect the existence of functional group which helps in the flocculation process. Hydroxyl and carboxyl group was detected from the FTIR analysis. The textile wastewater treated effluent was analysed for colour and COD reduction by coagulation (FeCl3) and flocculation (P and PAM) using a standard jar test apparatus.
