Abstract
A composite Hydrogel of carboxymethyl cellulose/acrylamide/powdered activated carbon (CMC/AM/PAC) were prepared by ɣ-irradiation and characterized by spectroscopic and electron microscopic techniques. The effect of monomer concentration on the percentage of composite hydrogel formation was studied. The composite hydrogel content reached the maximum gel percentage at radiation dose of 25 kGy, the formed composite was used for removal of natural organic matter (NOM) from raw water. The (NOM) uptake increased by increasing the pH of the medium until reached a maximum value at (pH5).The increase in contact time led to increase of the amount of (NOM) adsorbed until the equilibrium was reached within for (CMC/AM/PAC) composite Hydrogel.The optimum adsorbent dose of 0.4 g/L for (CMC/AM/PAC) composite Hydrogel. The potential applications of the newly sorbents is extraction (NOM) from real samples from raw water from Nile Rosetta branch. Also, Trihalomehanes (THM's) produced as disinfection by-products (DBPs) formed from the reaction between chlorine and (NOM) were removed using the composite Hydrogel by a 1 minute rapid mix stage at 150 rpm followed by a 20 min flocculation stage at 40 rpm and a 30 min settlement period. Also, it is noticed that the prepared composite Hydrogel has the ability to remove NOM up to 66.8%.
