| AbstractA sinple and sensitive photometric rnethod for the trace determination of metoclopramidelras been worked olri .The rnethod is based on the diazotization reaction of thedetet'tnination in acidic medium with the coupled o,-naphthol,to form purplisli violet watersoiubie azo dye that shows maximurn absorption at 549nm with molir absorbtivity of3.85x104 l.mol-l.cm-l.Bee.'s larv is obeyed over the concentration range 12.5-200pg ofmetoclopramide in final volume of 25m1,i.e.0.5-8pprn with the relative enor of -0.2 - +1.3atrd a relative standard deviation 0.68-2.17%.Morever,the method does not require eithertemperature | ||
