Rice husk ash (rha), coal fly ash (cfa) and palm oil fuel ash (pfa) as a potential sorbent for manganese removal _Mohd Nor Ismilhadi Che Soh_A9_2011_875004122_NI
Penyingkiran mangan dalam air merupakan satu perkara yang penting kerana pelbagai isu sensitif dan menjadi semakin penting dengan peningkatan aktiviti perindustrian. Dalam menangani pencemaran logam berat dalam ekosistem, pendekatan yang sesuai perlu dijalankan untuk mengatasinya. Terdapat banyak kaedah yang dapat dilakukan untuk merawat air buangan seperti pengoksidaan, pengklorinan, Ozonisasi, presipitasi kimia dan juga filtrasi membran, namun pemilihan kaedah pemprosesan air kumbahan berdasarkan kepada kepekatan mangan dan kos rawatan. Tujuan utama kajian ini adalah untuk menerokai proses penyingkiran mangan daripada air buangan sintetik menggunakan kaedah resapan dengan menggunakan gabungan bahan serap dari abu sekam padi (RHA), abu arang batu terbang (CFA) dan juga abu kelapa sawit (PFA). Bahan- bahan mentah ini didapati daripada sisa industri. Kajian ini akan melihat setakat mana kebolehan RHA/CFA/PFA bagi menyingkirkan mangan dari air buangan sintetik. Keputusan daripada kajian menunjukan masa pengoncangan optimum adalah 50 minit, tahap optimum pH adalah pH 8, kadar pengoncangan 190rpm dan penyerapan berupaya menyerap mangan sehingga lebih 90% pada konsentrasi 300mg/L. Kajian ini juga akan melakukan analisis mengenalpasti sifat-sifat fizikal dan kimia penyerap. ___________________________________________________________________________________ The removal of manganese from water is an important problem due to various sensitive issues and becoming more important with the increase of industrial activities. In order to solve heavy metal pollution in the ecosystem, it is important to bring applicable solution to the subject. There are several methods to treat the manganese contaminated effluent such as, oxidation, chlorination, ozonation, chemical precipitation and also membrane filtration, but the selection of wastewater treatment methods is based on the concentration of manganese and the cost of treatment. This study is focused on the removal of manganese from synthetic wastewater by using adsorption method with the sorbent being the combination of rice husk ash (RHA) palm fuel ash (PFA) and coal fly ash (CFA). These materials were obtained from the waste industrial. This study tried to determine how effective the sorbent in removing manganese from wastewater. This study reveals that the optimum shaking time for the adsorption is 50minutes, the optimum pH is 8, the optimum shaking rate is 190rpm and the adsorption was able to remove up the manganese with nearly 90% with concentration 300 mg/L. This study also was determined the characteristic of the sorbent by chemical and physical analysis.
