description P oly 2-hydroxyethyl methacrylate-co-acrylic acid /diatomite hydrogel composite DHC materials were synthesized using in situ free radical addition polymerization technique. The effects of particle size and amount of diatomite were investigated on swelling properties such as the swelling degree SD , equilibrium swelling degree ESD and water retention WR of DHC. The particle size and amount of diatomite were not affected clearly in the swelling properties. The synthesized DHC with the particle size of -45μm and the amount of 5 wt % of diatomite showed the highest swelling properties. The SD g/g , WR % and ESD % values of hydrogel were increased up to 29.2, 45.5 and 96.7 from 1.1, 41.3 and 89.3 by adding diatomite into the structure of hydrogel, respectively. The hydrogel and DHC were characterized using Fourier transform infrared spectrometer FTIR and an optical microscope. Also, their thermal behavior was analyzed by differential scanning calorimeter DSC . The FTIR spectrums showed that diatomite incorporated into the hydrogel matrix at the high amount of diatomite. The DSC results indicated that the glass transition temperature Tg and melting temperature Tm of hydrogel increased with the addition of 2 wt % diatomite. The adsorption studies were performed using the hydrogel composite including 5 wt % of diatomite
