2,4-DNP is also used as an intermediate to make dyes, photochemicals, and explosives and as an indicator for the detection of potassium and ammonium ions .
2,4-DNP is considered to be highly toxic to humans, with a lethal oral dose of 14 to 43 mg [kg.
Only a few studies using AOP for the destruction of 2,4-DNP have been published.
The present study was focused on the destruction of 2,4-DNP with [O.
The solutions were prepared dissolving 2,4-DNP in twice-distilled water.
The volume of fresh 2,4-DNP solution in the reactor was 0.
7 L of fresh 2,4-DNP solution in the cylindrical glass reactor with magnetic stirring.
The progress in the degradation of 2,4-DNP was followed with a high performance liquid chromatograph ("Millichrom", USSR) equipped with a UV-spectrophotometer (190-360 nm).
The concentration of nitrate ions formed as a result of nitrogen mineralization of 2,4-DNP was measured with ion chromatography .
Acute toxicity of the treated 2,4-DNP solutions to Daphnia magna (Cladocera, Crustacea) was studied.
