Abstract Pengoptimuman penyingkiran ion kuprum (II) oleh bulu ayam yang dirawat dengan asid degan mengunakan kaedah satu factor pada satu masa (OFAT) dan kaedah sambutan permukaan (RSM) telah dikaji. Dalam kaedah OFAT, kesan pH (5-9), kepekatan awal logam (100 mg/l-900 mg/l), muatan biomassa (2g-6g) dan suhu (32oC-40oC) telah dikaji. Kaedah optimum bagi penyingkiran ion kuprum (II) adalah pada ph 8, kepekatan awal logam 100 mg/l, muatan biomassa (3g) dan suhu 36oC. Di dalam kaedah RSM, ia menunjukkan bahawa terma linear dan kuadratik bagi kempat-empat pembolehubah bebas mempunyai kesan yang signifikan atas penyingkirann peratusan ion kuprum (II). RSM juga memberikan keadaan optimum yang sama dengan peratusan penyingkiran ion Cu (II) pada 92.30%. Ia menunjukkan bahawa RSM meramalkan lebih tinggi penyingkiran ion kuprum (II) berbanding dengan kaedah OFAT. Kajian kinetic untuk penyingkiran ion kuprum (II) menggunakan bulu ayam yang telah dirawat dengan asid dijalankan pada kepekatan awal logam dalam sistem kelompok. Bulu ayam yang dirawat dengan asid menunjukkan keafinitian yang tinggi menyingkirkan ion logam dan berpadanan dengan model kinetic pseudo kedua. _______________________________________________________________________________________________________ The optimization of copper (II) ion removal by pretreated chicken feathers using One Factor at A Time (OFAT) method and Response Surface Methodology (RSM) methods were investigated. In OFAT method, the effect of pH (5-9), initial metal concentration (100 mg/l – 900 mg/l), biomass loading (2g-6g) and temperature (32oC-40oC) for removal of Cu(II) ions was studied. The highest percentage of copper removal was achieved at pH 8, initial metal concentration of 100 mg/l, biomass loading of 3g and at temperature of 36oC. RSM method showed that the linear and quadratic terms of these four independent variables had significant effect towards the percentage of Cu(II) ions removal. RSM also gave the same optimal conditions and the percentage of copper (II) removal was at 92.30%. This means that RSM had predicted a higher Cu(II) ion removal compared to OFAT method. The kinetic studies for Cu(II) ion removal by pretreated chicken feather were carried out at different concentration in a batch system. Cu (II) ion removal best fits the pseudo-second order model.
