摘要
The paper reports the spectral characteristics and kinetics of phototransformation for selected priority organic chemicals, like high volume product chemicals (HPVC) e.g. naphthalene, 4-chloro-2-methylphenol, and pesticides e.g. azinphos-methyl, phosalone, isophenphos, phenmediphan, acifluorphen, metholachlor, mecoprop, bentazone, lenacil, monolinuron, parathion methyl, parathion ethyl. The compounds are dissolved in aqueous solution and irradiated with a solar light simulator. The use of LC-MS/MS equipped with APCI (atmospheric pressure chemical ionisation) and ESI (electrospray interface) has given the possibility of screening analysis and identification of breakdown products.
