Preparation of hydrogels based on carboxymethyl cellulose (CMC) using direct radiation grafting technique for removal of organic contaminant such as 4‐chlorophenol and 2,4‐dichlorophenoxyacetic acid (2,4‐D) was carried out. The prepared hydrogels which are composed of individual radiation grafting of methacrylic acid onto CMC to form poly(CMC/MAA) the other hydrogel composed of binary acrylamide/methacrylic acid grafted onto CMC to form poly(CMC/MAA:AAm) hydrogels. The two selected composition poly(CMC/MAA:AAm) (1/60:40 wt%) poly(CMC/MAA) (1:20) wt% hydrogels due to its high chelating properties obtained from our previous work by the same authors. The properties of the selected two prepared hydrogels were evaluated by using different analytical tools such as Fourier transform infrared (FTIR), X‐ray diffraction (XRD), and thermogravimetric analysis (TGA). The gel (%) and the swelling behavior of poly(CMC/MAA:AAm) is higher than poly(CMC/MAAc) hydrogel. It is found that the adsorption capacity of poly(CMC/MAA) hydrogel (1:20 wt%) toward 4‐chlorophenol and 2,4 dichlorophenoxy acetic acid was higher than that of poly(CMC/MAA:AAm) (1/60:40 wt%) hydrogel. Also The obtained results showed that the adsorption capacity of both poly(CMC/MAA:AAm) (1/60:40 wt%) and poly(CMC/MAA) (1:20) wt% hydrogels toward 2,4 dichlorophenoxy acetic acid was higher than of 4‐chlorophenol.
