In this study, two types of adsorbent including activated carbon and bio-sorbent were produced from Palm fiber wastes (PFW), which were activated by phosphoric acid. The influence of adsorbent type and phosphoric acid concentration on methylene blue adsorption was investigated. The most optimum adsorbent was determined based on adsorption capacity and removal percentage of each adsorbent. The result shows that 9.984 mg/g of adsorption capacity and 99.84% of removal percentage were achieved in 90 minutes’ adsorption, which demonstrates the huge potential of bio-sorbent and was chosen to be the most optimum adsorbent based on methylene blue removal. The characterization of bio-sorbent was then investigated using FTIR and SEM. FTIR result shows that bio-sorbent contains cellulose which affected the adsorption process while SEM result shows the cleaner pores and surface compared to bio-sorbent before activation.

A family of mesoporous multilamellar silica vesicles has been successfully synthesized by using P123 as structure directing agent and hexane as co-surfactant. The structure was characterized with XRD, TEM, and N2 adsorption-desorption isotherms. This multilamellar silica vesicle materials process high specific area, large pore volume, and a bimodale pore size distribution. Furthermore, these materials are stable when the surfactant is removed at 530 oC.
