Abstract

A rapid sensitive and reliable mixed indicator paper strip impregnated with dimethyl yellow (0.05%), cresol red (0.1%) and mercuric chloride (1.0%) in methanol was developed for the detection of phosphine in air at the permissible level (TLV). The paper strip turns red in the presence of phosphine. It is highly sensitive and has a better shelf-life than indicator strips inpregnated with dimethyl yellow plus mercuric chloride or cresol red plus mercuric chloride.
