摘要

Polysiloxane materials containing residual thiophosphonic acid groups ≡Si(CH_2)_3NHP(S)(OC_2H_5)_2 in the surface layer have been prepared by sol-gel template methods (S_(sp) = 240 - 670 m~2/g; V_s = 0.19 - 0.41 cm~3/g; d = 3.3 - 4.5 nm). It was supposed that synthesized silicas are able to adsorb mercury(II) ions from nitric acid solutions (their SSC can be close to 450 mg/g). It was shown that the complexes in 1:1 ratio were formed in the surface layer. The excessive sorption of metal ions was shown to be due to partial hydrolysis of ethoxy-groups attached to the phosphorus atom.
