Application of flow microcalorimetry to analytical problems-I. Determination of organophosphorus pesticides by inhibition of cholinesterase.
Flow microcalorimetry has been applied to the determination of organophosphorus pesticides by inhibition of cholinesterase. One direct inhibitor (TEPP) and one latent inhibitor (parathion) were investigated. The former is determinable at concentrations of about 10(-6)M and the latter at about 10(-4)M. The inhibitory power of parathion is increased if methanol is used as solvent.
