Magnetic activated carbon (MAC) is found to be effective for the adsorption of methylene blue due to its physico-chemical properties such as strong adsorption of magnetization. The use of activated carbon (AC) for methylene blue adsorption was ineffective compared to MAC. MAC was prepared by incorporating different types of iron powder and chemicals [sodium dodecyl sulphate (SDS), citric acid (CA), dimethicone (D350), and epichlorohydrin (C3H5ClO)] to strengthen the magnetism and stabilize the MAC. The methylene blue test and iodine test were tested on different samples. Characterization test on physical and chemical properties was carried out using Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD). The yield of MAC was higher because of the addition of magnetic particles. The incorporation of magnetic particles had been proven by the SEM and XRD analysis that showed the presence of iron compound. The performance study of the adsorbent sample showed that MAC_A3II presented better qualities with highest removal percentage (98.81 % of removal) in methylene blue adsorption and low magnetic contact time that showed strong magnetism. MAC_A3II was prepared by incorporating iron powder and treated by using sodium dodecyl sulphate (SDS). Among all the adsorbent sample, MAC_B2III performed the weakest quality because the dye removal percentage was low, and the preparation process was complicated compared with others.

For the treatment of dye wastewater, it is of great significance to develop new adsorbents with high adsorption capacity and good separation effect. In this study, the Fe-Co magnetic activated carbon material (CN-Fe-Co-AC) was first prepared by high-temperature calcination. CN-Fe-Co-AC is physically characterized by various methods. CN-Fe-Co-AC can efficiently and quickly remove the organic dyes methylene blue (MB) and acid blue 80 (AB80). The adsorption of MB and acid blue based on CN-Fe-Co-AC adsorbent is mainly through the specific surface area and the functional groups on the surface. During this recovery process, the adsorption activity of CN-Fe-Co-AC for MB and AB80 decreased slightly. Kinetic data can be described using a Pseudo-second-order model and the data for adsorption equilibrium can be described using the Langmuir isotherm. The theoretical adsorption capacities of MB and AB80 are 104.82[Formula: see text]mg/g and 26.94[Formula: see text]mg/g, respectively. After repeated use of five times, the removal rate of MB exceeded 96%, and the removal rate of AB80 exceeded 75%. The excellent adsorption performance and recyclability of CN-Fe-Co-AC indicate that this material has certain potential application value.

Phosphoric Acid Concentration

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.
