摘要：

The photodegradation of humic acids (HA) in aqueous solution was carried out in the presence of Fe(III) and oxalate, and the influence of inorganic ions, such as Ca2+, Mg2+, HCO3- and H2PO4- on HA removal was investigated. 88.9 % removal of HA in solution was reached after 75 min with Xe lamp irradiation (lambda > 290 nm) when the initial concentrations of oxalate and Fe(III) were 0.5 mmol/L and 0.2 mmol/L, respectively. The photodegradation of HA by Fe(III)/oxalate system is inhibited by the presence of Ca2+, Mg2+, HCO3- and H2PO4- in solutions.
