TL;DR: The removal of 17 pesticides found in agro-wastewater from washing of containers and phytosanitary treatments equipment, has been carried out using sodium persulfate (Na2S2O8) at pilot plant scale under natural sunlight using a photoreactor to optimize the Na2S1O8 concentration on the rate constants of the found pesticides.

TL;DR: In this article, the photocatalyzed degradation of a mixture of six pesticides (malathion, fenotrothion, quinalphos, vinclozoline, dimethoate and fenarimol) with endocrine disrupting activity has been studied in sewage wastewater effluent under natural sunlight at pilot plant scale.

TL;DR: Dispersive liquid-liquid microextraction was used to preconcentrate three spirocyclic tetronic/tetramic acid derivatives and five neonicotinoid insecticides previously extracted from fruit and vegetable matrices with acetonitrile, finding only thiamethoxam was detected in a lemon sample at a concentration close to the quantification limit.

TL;DR: Comparison of catalysts showed that ZnO is the most efficient for the removal of such insecticides in optimal conditions and at constant volumetric rate of photon absorption.

TL;DR: Results carried out at pilot plant scale show that addition of ZnO in tandem with Na2S2O8 strongly enhances degradation rates compared with photolytic test, and photocatalytic oxidation using ZNO is an area of environmental interest for the treatment of polluted water, particularly relevant for Mediterranean countries where solar irradiation is highly available.
