Solar photocatalytic degradation of some hazardous water-soluble pesticides at pilot-plant scale
The technical feasibility and performance of photocatalytic degradation of six water-soluble pesticides (cymoxanil, methomyl, oxamyl, dimethoate, pyrimethanil and telone) have been studied at pilot-plant scale in two well-defined systems which are of special interest because natural solar UV light c...

| description | The technical feasibility and performance of photocatalytic degradation of six water-soluble pesticides (cymoxanil, methomyl, oxamyl, dimethoate, pyrimethanil and telone) have been studied at pilot-plant scale in two well-defined systems which are of special interest because natural solar UV light can be used: heterogeneous photocatalysis with titanium dioxide and homogeneous photocatalysis by photo-Fenton. TiO
2 photocatalysis tests were performed in a 35
L solar pilot plant with three Compound Parabolic Collectors (CPCs) under natural illumination and a 75
L solar pilot plant with four CPC units was used for homogeneous photocatalysis tests. The initial pesticide concentration studied was 50
mg
L
−1 and the catalyst concentrations employed were 200
mg
L
−1 of TiO
2 and 20
mg
L
−1 of iron. Both toxicity (
Vibrio fischeri, Biofix
®) and biodegradability (Zahn–Wellens test) of the initial pesticide solutions were also measured. Total disappearance of the parent compounds and nearly complete mineralization were attained with all pesticides tested. Treatment time, hydrogen peroxide consumption and release of heteroatoms are discussed. |
