Abstract :In present study acrylic acid insert ignore into journalissuearticles values(AAc); and sodium styrene sulfonate insert ignore into journalissuearticles values(SSS); were grafted onto non-woven polyethylene fabric using pre-irradiation method and the grafted adsorbent is employed for Crinsert ignore into journalissuearticles values(III); and Pbinsert ignore into journalissuearticles values(II); adsorption. After irradiation of the non-woven polyethylene fabrics with 50 kGy radiation dose the grafting reaction was carried out at 80º C with monomer solution consisted of 30% AAc, 10% SSS and 4% NaCl in water. A high graft yield of 270% was achieved. Fourier Transform Infrared, Scanning Electron Microscopy and Thermo-gravimetric Analysis were used to analyze the adsorbent. Pb insert ignore into journalissuearticles values(II); and Cr insert ignore into journalissuearticles values(III); adsorption from synthetic aqueous solution was attempted by the grafted adsorbent. Adsorption study was accomplished by changing the contact time, pH and initial metal ion concentration. Contact time 48 h and initial metal concentration 1000 ppm were found optimum for all the metal ions studied. pH 6.2 and 5 was observed best for Pb insert ignore into journalissuearticles values(II); and Crinsert ignore into journalissuearticles values(III); adsorption respectively. Kinetic adsorption data fitted better with pseudo-second-order equation than pseudo-first-order. Good correlation of experimental data with Langmuir isotherm model suggested monolayer adsorption. Langmuir equation showed that the maximum adsorption capacity for Pb insert ignore into journalissuearticles values(II); was 38.46 mg g-1 and Cr insert ignore into journalissuearticles values(III); was 111.11 mg g-1. Experiment on desorption of metal ions and reuse of the adsorbent depicted good results. Adsorbent also showed efficient adsorption of Crinsert ignore into journalissuearticles values(III); from real waste water. From all the findings it can be expected that the AAc-SSS grafted PE fabric can successfully eliminate Crinsert ignore into journalissuearticles values(III); and Pbinsert ignore into journalissuearticles values(II); from industrial waste water.
