    Adsorptive removal of malachite green dye using durian seed-based activated carbon
    (Springer, 2014) Mohd Azmier Ahmad; Norhidayah Ahmad; Olugbenga Solomon Bello
    Chemically prepared activated carbon derived from durian seed (DSAC) was used as adsorbent to adsorb Malachite green (MG) dye. The prepared DSAC was characterized using Brunauer-Emmet-Teller(BET), Fourier transform infrared (FTIR), scanning electron microscope (SEM), and proximate analysis,respectively. Batch adsorption studies were carried out for the removal of MG dye from aqueous solutions by varying operational parameters like contact time, initial MG dye concentration, solution temperature, and initial solution pH. Maximum dye removal of 97 % was obtained at pH 8. This work provided an attractive adsorbent for the removal of MG dye from wastewaters.

    Removal of residual oils from palm oil mill effluent by adsorption on natural zeolite
    (Springer, 2012) M. A. Shavandi; Z. Haddadian; M. H. S. Ismail; N. Abdullah; Z. Z. Abidin
    The adsorption of residue oil from palm oil mill effluent using natural zeolite was investigated in this study. The adsorption was performed in batch mode, and the effect of different operational parameters such as pH, dose of adsorbent, stirring rate, contact time and initial oil concentration were explored. It was found that the pH plays a major role in the adsorption process. Isotherm data best fitted with the Freundlich model, and kinetic data followed the pseudo-second-order kinetic model.
