Abstract

The present work was aimed at evaluating the removal of methylene blue by palm fatty acid distillate-based adsorbents. The adsorbents at different weight ratios of palm fatty acid distillate (PFAD) to palm kernel shell (PKS) were prepared at 600 °C for 2 hours. Results show that the yield of adsorbent upon heat treatment decreased with increasing weight ratio, with yield as low as 0.53% was recorded by adsorbent derived by using only PFAD. The methylene blue adsorption data show a promising performance of PFAD-based adsorbents as compared to that of PKS-adsorbent (char) with q_e = 7.6 mg/g at C_o = 20.8 mg/L. To conclude, PFAD is a potential candidate of dye adsorbent.

Abstrak

Tujuan kajian ini adalah untuk menilai penyingkiran metilena biru oleh penjerap berasaskan distilat asid lemak sawit. Penjerap pada nisbah berat distilat asid lemak sawit (PFAD) kepada isirong sawit (PKS) disediakan pada 600 °C selama 2 jam. Keputusan menunjukkan bahawa hasil penjerap setelah rawatan haba berkurang dengan peningkatan nisbah berat, dengan hasil serendah 0.53% direkodkan oleh penjerap terbitan PFAD sahaja. Data penjerapan metilena biru menunjukkan prestasi menjanjikan oleh penjerap berasaskan PFAD berbanding penjerap berasaskan PKS (arang) dengan q_e = 7.6 mg/g pada C_o = 20.8 mg/L. Kesimpulannya, PFAD ialah calon berpotensi sebagai penjerap pencelup.
