Indonesia is the world’s largest crude palm oil (CPO) producer and consumer in 2014. Components that affect the quality of CPO are diglycerides (DAGs) and free fatty acids (FFA). DAGs in palm oil are known as the precursor of 3-MCPD esters, while higher content of FFA could influence the oil stability. The contact of CPO with adsorbent could affect the present of DAG and FFA in CPO.

This study has focused on the synthesis of lanthanum-, cerium- and calcium-functionalized adsorbents to remove heavy metal ions from aqueous solutions. Avocado seeds were used as a feedstock to obtain carbon-based adsorbents via pyrolysis and these adsorbents were further functionalized with lanthanum, cerium and calcium species using different experimental conditions to improve its adsorption properties. These adsorbents were utilized for the adsorption of heavy metals from aqueous solutions. At tested experimental conditions, the raw adsorbent showed an adsorption capacity of 7.04, 10.91, 11

The available conventional methods for the treatment of colored waste water are expensive and produce large amount of sludge at the end of the process. In many methods, adsorption is known to be a promising technique. Commercially available activated carbon from coal used as an adsorbent material is an expensive and non-renewable has restricts its use. Adsorbent from agricultural wastes and plant biomass are considered to be low-cost candidates.

By varying adsorbate concentration, temperature, contact time, pH, and adsorbent weight, the capacity of non-modified (NM) and modified (M) sawdust adsorbents to adsorb Ni2+ ions were studied in this work. The adsorption of Ni (II) ions rose as the adsorbent weight increased but reduced as the adsorbate concentration increased. Adsorption was greatest at pH 6, with the NM and M adsorbents removing 95.09 and 96.95% of Ni2+ ions, respectively. The highly dependent nature of the percent removal on operational variables was established by employing Analysis of Variance (ANOVA) as well as the Bonfe

A new Oil-Mineral Aggregate with bentonite and calsium hydroxide and sawdust has been done. Through several dozens of experiments, the coagulation efficiency with bentonite and Ca(OH)2 and sawdust is 94.53%. The functions of bentonite are coagulation, adsorption and emulsification. Calsium hydroxide is a good coagulant-mate, and strengthen the coagulating function of bentonite. It can be used as the source of calcium ions, which can strongly adsorb on both bentonite and oil droplets, and is helpful for the coagulation between bentonite and oil droplets.
