Photocatalytic Degradation of Thiram (Fungicides) under Visible Light Irradiation

Abstract

Pesticides in the different form are toxic to the environment and removal of its form the various sources is a difficult task. The thiram undergoes photocatalytic degradation under visible light when prepared TiO2∼PVA polymer composite was used as a photocatalyst. The data represent that prepared TiO2∼PVA polymer composite is a more efficient photocatalyst than the neat TiO2. Photocatalytic efficiency of prepared TiO2∼PVA polymer composite was measured in term of no adsorption of pollutant, higher degradation rate and act as a photocatalyst under visible light irradiation. 150 minutes are required for the complete degradation of the thiram. The end products of photocatalytic degradation of thiram are CO2, nitrate and sulphate.

An Efficient Photocatalytic Degradation of Methyl Blue Dye by using Synthesised PbO Nanoparticles

“…The dye like rhodamine B 11 , reactive red-2 12 and malachite green 13 was removed by activated carbon. The herbicide (thiram) was photocatalytically degraded by using TiO 2 in presence of visible light 14 . The PbO nanoparticles also used in sensor 15 , Li -ion batteries 16 , Lead -acid batteries 17 and biomedical application 18 .…”

Degradation of thiram in water, soil and plants: a study by high‐performance liquid chromatography

“…It has been reported that thiram degrades faster in the field than in the greenhouse, and as a wettable powder than as an emulsion (Vyas and Nene, ). However, a few other reports have been confined to its photo‐ and microbial degradation (Shirkot and Gupta, ; Gao et al , ; Thakare and Bhave, ; Haque and Muneer, ). Thiram was rapidly degraded in a water solution when irradiated with UV light.…”

Biological Visual Detection for Advanced Photocatalytic Oxidation toward Pesticide Detoxification

“…24 Additionally, Jiang et al summarized many kinds of microbes with functions of degrading various pesticides. 25 Stenotrophomonas acidaminiphila BJ1, epigallocatechin gallate, Bacillus subtilis WB800, and procyanidolic oligomers were also applied to reduce CTL residues. 3,10,26,27…”

“…Ozonation, FeGAC/H 2 O 2 , and TiO 2 /H 2 O 2 are effective advanced oxidation techniques in the mineralization of CTL into CO 2 , H 2 O, and NH 3 . ,, Singh et al controlled the release of TMTD by synthesizing supramolecular beads containing a certain proportion of kaolin and bentonite, which can be used for the safe handling of thiram . Additionally, Jiang et al summarized many kinds of microbes with functions of degrading various pesticides Stenotrophomonas acidaminiphila BJ1, epigallocatechin gallate, Bacillus subtilis WB800, and procyanidolic oligomers were also applied to reduce CTL residues. ,,, …”
