Methylene blue adsorption on cellulose extracted from oil palm (elaeis guineensis) trunk / Noorfazlin Ahmad Azmi

The potential of oil palm trunk cellulose (OP Cellulose) powder as adsorbent
to removing methylene blue (MB) was observed. The functional group of OP
cellulose was characterized by using Fourier Transform Infrared (FTIR). The
pH of zero point charge was 5.10. The effect of pH, dosage, initial
concentration and contact time were investigated. The adsorption equilibrium
was achieved after 10 minutes. The MB maximum uptake was pH 10 with
90.41 % removal. Pseudo-first order and Pseudo-second order kinetics models
were applied. The result showed that pseudo-second order achieve high
correlation (R2 >0.9999). The adsorption fitted well with Langmuir isotherm
equation. In this study suggested that OP cellulose are effectively to remove
MB.
