Description

A functional adsorbent with specific selectivity for heavy metals was prepared by radiation-induced grafting polymerization of bis [2-(methacryloyloxy) ethyl] phosphate (BMEP) onto polyethylene/poly propylene (PP-PE) non-woven fabric. Effects of monomer, solvent and radiation dose on degree of grafting were investigated. FTIR and SEM were used to characterize the prepared adsorbents as well as to confirm that the grafting polymerization was effective. Efficiency of heavy metal adsorption of the adsorbents were done by UV spectrophotometry, using a calibration curve made from standard CuCl$_2$ solution. Effects of degree of grafting (from 107 to 326%) on adsorption efficiency were analyzed. Results showed that degree of grafting in the range of 130 – 170% led to maximum efficiency of Cu$^{2+}$ adsorption in the range of 80 – 85%. These preliminary results were used for an upscaling of adsorbent preparation. A prototype for a fix-bed column (height = 35 cm, diameter = 3 cm) was designed. The adsorption capacity of Cu$^{2+}$ of the adsorbent using a prototype fix-bed column was 0.129 mg/cm$^2$, showing its potential to be utilized for removal of heavy metals in a portable wastewater treatment system.
