Thiol Functionalized Aloe Vera Fibre Filter: A Simple Portable Water Filter For Heavy Metal Ion Removal

Abstract

A novel high efficient filtration system for heavy metal ion adsorption from water bodies has been developed. It is a costefficient filtration system that removes Pb 2 + and Cd 2 + ions effectively in an efficient manner. Aloe vera fibre that has been alkali-treated and given a thiol functional is stuffed into a porous tube with a packing density of 0.2, and the porous tube is covered with polyacrylonitrile nanofibre. Functionalized aloe vera fibre and PAN nano fibres were characterized by various techniques such as X-ray difractiomatry (XRD), Attenuated total reflection-fourier transforms infrared spectroscopy (ATR-FTIR), thermo gravimetric analysis (TGA), tensile tester and scanning electron microscopy (SEM). Furthermore, the heavy metal ion removal efficiency of filtration system was examined by inductively coupled plasma-optical emission spectrometry (ICP-OES). Inductively coupled plasma-optical emission spectrometry (ICP-OES) was used to evaluate the effectiveness of the filtering system's ability to remove heavy metal ions. In order to conduct column adsorption tests, the initial metal ion concentration was varied. The breakthrough curves of the trials were then analysed. With the aid of Thomas adsorption isotherm and Yoon-Nelson model, the adsorption mechanism of thiol functionalized aloe vera fibre was thoroughly investigated. The portable filter has the ability to continuously treat waste water, which is a useful function.

Reduction of water turbidity with bio-flocculent: Use of Aloe Vera Gel

“…of plants as potential sources of flocculants-coagulants [6]. Interestingly, Aloe Vera Gel (AVG) has been reported to be a promising natural material to replace chemicals in the coagulation-flocculation treatment process [11,12]. Figure (1) shows the chemical structure of AVG and table (1) shows its chemical composition.…”
