This study explored the low-cost adsorbent of orange peel and spent tea leave for Methylene Blue (MB) and Remazol Brilliant Blue R (RBBR) dyes removal from aqueous solutions. The removal rate and adsorption capacity on the adsorption of dyes were investigated using the batch adsorption study. The present study indicates that the MB was easier to remove by both orange peel and spent tea leave compared to RBBR with percentage removal of 95.72 % and 99.02 % respectively. The effects of morphology,

The result proved that orange peel and spent tea leave were promising material as an alternative adsorbent for the removal of MB from aqueous solution. Abstrak Kajian ini menggunakan adsorben kos rendah dari kulit limau dan serbuk teh yang telah digunakan untuk penyingkiran dai Methylene Blue (MB) dan Remazol Brilliant Blue R (RBBR) daripada larutan akueus. Kadar penyingkiran dan kapasiti penjerapan pewarna telah dikaji menggunakan cara 'batch method study'. Kajian ini menunjukkan bahawa MB adalah lebih mudah untuk disingkirkan oleh kedua-dua jenis adsorben kulit limau dan sisa serbuk teh berbanding penyingkiran RBBR di mana masing-masing dengan peratusan penyingkiran adalah 95.72 % dan 99.02 %. Kesan morfologi, kumpulan berfungsi dan kawasan permukaan adsorben dikaji dengan menggunakan FESEM, FTIR dan BET. Hasil kajian membuktikan bahawa kulit limau dan sisa serbuk the adalah bagus sebagai bahan penjerap alternatif untuk penyingkiran MB daripada larutan akueus.
