The functional composite-type particle PMAA/SiO2, which was prepared by grafting polymethacrylic acid (PMAA) onto the surface of silica gel particles (SiO2), was used as solid adsorbent, and the static adsorption experiments for pirimicarb in water were performed. The adsorption mechanism of PMAA/SiO2 for pirimicarb in water was mainly studied via examining the effects of various factors, such as pH value, concentration of sodium chloride (NaCl) and temperature on the adsorption capacity. In order to confirm further the adsorption mechanism put forward, the interaction between the monomer methacrylic acid and pirimicarb was investigated by using UV spectral absorption method. The adsorption behaviour of PMAA/SiO2 for pirimicarb in carbon tetrachloride (CCl4) was also studied. The experimental results showed that the functional composite-type particle PMAA/SiO2 had strong adsorption ability for pirimicarb. The driving force of the adsorption was the synergism of electrostatic, hydrogen bond and hydrophobic interactions. Among them, the electrostatic interaction was the main driving force. The adsorption capacity decreases with the enhancement of temperature; as salinity of the solution increases, the adsorption capacity decreases; when pH<8, the adsorption capacity increases with the increase of pH value, decreases with the increase of pH value as pH>8, and when pH=8, the adsorption capacity has a maximum.
