“…About 4-5 wt.% of OPDC was generated from the feed fresh fruit bunches (FFB), comprising over 70% of moisture and 12% of residual oil. At the same time, the remaining contains cellulose, lignin, inorganic (ash residue), and organic material (nitrogen, phosphorus, and potassium) (Sahad et al, 2014;Yusoff et al, 2019). The vast amount of OPDC has poorly created an environmental problem since it is usually disposed of and neglected at the factory side, which is expected to decompose without any treatment.…”

“…The vast amount of OPDC has poorly created an environmental problem since it is usually disposed of and neglected at the factory side, which is expected to decompose without any treatment. Previous studies have explored alternative use of OPDC as animal feed, fertilizer, or composting material (Yahya et al, 2010), biofuel (Razak et al, 2013), biogas fermentation (Eko & Chaiprasert, 2020;Tepsour et al, 2019), bio-adsorbent of heavy metals from wastewater (Yusoff et al, 2019), cellulose extraction, and crude oil recovery (Anuar et al, 2018;Sahad et al, 2014).…”

Numerous agricultural wastes are well-defined as low-cost sources and rich in silica content. The residue of oil palm wastes combustion seems a promising silica source and can be recovered through a straightforward method. In this study, the combustion followed by an alkaline extraction method was employed to extract high purity of silica. The oven-dried oil palm decanter cake (DOPDC) was heated at combustion temperatures of 600, 700, 800, and 900°C to produce OPDC ashes (OPDCA), followed by an alkaline extraction using 5M of NaOH solution. Thermogravimetric analysis (TGA) was used to observe the thermal behavior of DOPDC where the suitable combustion temperatures to produce silica ranged between 600 and 1000 ℃. X-Ray Fluorescence (XRF) analysis showed that silica contents were 31-36% after combustion, increasing to 76.95% after the chemical treatment. Moreover, the spherical shape of the silica was observed through electron microscope analysis. It was represented by the aggregation of silica after going through chemical treatment. The X-Ray Diffraction analysis also proved that the amorphous silica was produced, characterized by the hump-shaped spectrum. The infrared analysis confirmed that the silica had been successfully extracted from OPDCA by the presence of silica functional groups shown in the spectrum.

In this study, the thiol-functionalized resin (PMA-SH) was prepared directly by a one-step reaction of polymethyl acrylate resin (PMA) and 1,2-ethanedithiol, and it was applied to the adsorption of Pb 2+ , Ni 2+ , and Hg 2+ in aqueous solution. The effects of initial concentration, temperature, contact time, and electrolyte on the adsorption of Pb 2+ , Ni 2+ , and Hg 2+ were investigated. At 308 K, the saturated adsorption capacity of PMA-SH on Pb 2+ , Ni 2+ , and Hg 2+ is found to be 0.94, 0.88, and 0.41 mmol/g, respectively. In addition, the experimental adsorption data were consistent with the Redlich-Peterson model and pseudo-second-order kinetic model. Overall, PMA-SH exhibited good reuse performance as well as excellent adsorption performance for Pb 2+ , Ni 2+ , and Hg 2+ .
