A new spot test for the detection of dithiocarbamate fungicides in soil and water

چکیده
A new spot test has been developed for the detection of dithiocarbamate fungicides such as mancozeb, propineb and zineb at nkg level in soil and water. The colour formation is based on the decomposition of dithiocarbamate to carbon disulphide which reacts with plumbite i ' alkaline medium to form a brown complex that finally converts to black lead sulphide. The coloured product exists as a bright brown-black colloidal solution in formaldehyde or glycerin or hydroxylamine hydrochloride.

Photodegradation and flow-injection determination of dithiocarbamate fungicides in natural water with chemiluminescence detection.
A simple and rapid flow-injection method is reported for the determination of dithiocarbamate fungicides (maneb, nabam and thiram) based on chemiluminescence detection. The method involves the photodegradation of dithiocarbamate fungicides via UV light in an alkaline medium. Photoproducts are then reacted with luminol in the absence of an oxidant. Linear calibration graphs were obtained in the ...
