Abstract
Water pollution has been a major threat to our lives for a long time. This prevalent problem has become the cause that is jeopardizing the marine life as well as our health. It occurs when hazard and toxic substances spilt into river, lake, ocean or stream that degrade the water quality and rendering it lethal to the life. To mitigate of this challenging issue, a biocompatible compound, Zn Al Layered Double Hydroxide (LDH), has been designed and modified through the co-precipitation method. This synthesized compound was modified with phenyl pyruvate to improve its functionality. This synthesized and PPA-modified Zn Al LDH was subjected to characterization via FTIR, SEM, EDX, and XRD, which endorsed the intercalation of guest ions. Moreover, PPA-modified Zn Al LDH was applied for the sorption of organic dye Methyl Blue from water and optimized various parameters, including pH, dosage, volume, time, and temperature, and found that the best sorption was found at pH 10 with a dosage amount of 0.25g and a volume of 30 ml at 40 oC within 100 min. The adsorbent capacity was calculated at 92 mg/g. In addition, it was perceived through kinetic study and sorption isotherm that the pseudo-second-order equation is more applicable, which indicated that the sorption might be physio-sorption. Conclusively, the studied parameters and various isotherm models explained that PPA-modified Zn Al LDH has the ability to sorp the organic dye and can be utilized industrially.
