摘要：
The photochemical formation of hydrogen peroxide in the Kitagata lake water was monitored by a sensitive photometric method using leuco Crystal Violet as a color producing reagent The concentration of hydrogen peroxide increased with irradiation and reached equilibrium values ((1.8-2.4) X 10(-6) mol.dm-3). Suspended solids contributed to the formation of hydrogen peroxide. The decomposition rates of hydrogen peroxide in the dark were very small compared to the formation rates. About 25% of the superoxide generated photochemically did not lead directly to hydrogen peroxide formation.
