Synthesis of Magnetic Activated Carbon Treated with Sodium Dodecyl Sulphate

Abstract

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.

Characterizing Groundwater Turbidity Reduction by Using a Magnetic Biocarbon Adsorbent Composite (MBAC): Process Optimization

“…The magnetic biocarbon adsorbent composite (MBAC) is a combination of coconut shell (CS) derived activated biocarbon (ABC) impregnated with iron oxide particles. The coconut shells were carbonized in a 200 L modified carbonization drum through top lit up-draft (TLUD) approach [16]. The carbonized CS (CCS) pieces were washed, left to dry, then crushed into powder form, and sieved (Auto sieve shaker, Model: A060-01) before segregated into 5 particle size ranges (M: 300 < x ≤ 500; N: 150 < x ≤ 300; O: 75 < x ≤ 150; P: 45 < x ≤ 75; and Q: ≤ 45).…”

Rhodamine 6g Removal from Aqueous Solution with Coconut Shell-Derived Nanomagnetic Adsorbent Composite (Cs-Nmac): Isotherm and Kinetic Studies

“…Afterward, the carbonized CS was ground into powder. CS-NMAC was prepared following a previously described method with slight modifications (Sannasi et al, 2021;Wannahari et al, 2018). The specific surface area and pore volume of the carbonized CS powder were increased by subjecting it to KOH activation at a ratio of 1:3 (carbonized CS powder:KOH) with slow agitation.…”
