Microwave-Assisted “One-Pot” Acidolysis and Extraction for the Rapid Determination of Mancozeb in Fruit and Vegetable Samples

Table 3

CS₂ conversion of mancozeb and other DCTs fungicides (n = 6).

Compounds	Added of DTCs (μg)	Theoretical content of CS2 (μg)	Actual measured content of CS2 (μg)	Conversion rate (%)
Mancozeb	0.25	0.141	0.129 ± 0.0041	91.5 ± 2.9
Metiram	0.25	0.140	0.128 ± 0.0060	91.4 ± 4.3
Thiram	0.25	0.158	0.114 ± 0.011	72.2 ± 7.0
Propineb	0.25	0.131	0.108 ± 0.0072	82.4 ± 5.5

Note. The theoretical conversion rate is based on molar mass. 1 g of mancozeb produces 0.562 g of CS₂, 1 g of metiram generated 0.559 g CS₂, 1 g of thiram generated 0.632 g CS₂, and 1 g of propineb generated 0.525 g CS₂.
