In this study, sulfate radical concentration from 4 drip water points (PL1, PL2, SH, JG) in the Shihua cave have been monitored for three years, and those from the drip water point was monitored for two years. Drip discharges show three types of response to surface precipitation variations: rapid response, response with associated time-lag and stable. The results show that:(1) SO(superscript 2- subscript 4) concentration in rapid response drip water increases sharply during rain period and has a exponential relationship with drip rate;(2) in the drip water of lag response, SO(superscript 2- subscript 4) concentration has no significant incrcase during rainfall, but they show a increasing trend during a long-term monitoring;(3) SO(superscript 2- subscript 4) concentration at the stable drip site is low and has no obvious change during wet weason.

Different from the Lewis acidity nature of SO4(superscript 2-)/ZrO2/MCM-41, SO4(superscript 2-)/TiO2 and S2O8(superscript 2-)/TiO2 behave mainly Brnsted acidities. The strongest Brnsted acid sites are formed on SO4(superscript 2-)/TiO2 promoted with H2SO4, while Lewis acid sites on S2O8(superscript 2-)/TiO2 are even stronger than those on SO4(superscript 2-)/ZrO2/MCM-41, and the former which are generated when persulfate solution is used as sulfating agent.
