Prediction of conditions for use of spectrophotometric reagents: p-dimethylaminobenzilidenerhodanine as a spectrophotometric reagent for silver and palladium.
A method for theoretical estimation of the detection limits of spectrophotometric reagents is reported. The concentration limits of Beer's law when p-dimethylaminobenzilidenerhodanine is used for determination of silver and palladium are defined on the basis of the stability constants. Conditions for determination of 2-10mug, of Ag per 25ml and 1-5mug of Pd per 25ml with standard deviation 0.03mug per 25 ml are proposed.
