Indirect Determination of Sodium Cyclamate in Jelly Food by UV Spectrophotometry

A method for indirect determination of sodium cyclamate in jelly food by UV spectrophotometry was reported in this paper.Influential factors,including kinds of acid mediums,concentrations and amounts of HCl,NaNO2 and KI solutions required,and time of reaction were studied.Under the optimum condition.Beer′s law was kept in the range of 1.0-14.0 mg· L-1,with detection limit (3S/N) of 0.3 mg· L-1.Tests for precision and accuracy were made by standard addition method,and values of RSD′s (n=5) and recovery obtained were in ranges of 0.7%-1.3% and 102.6%-103.3% respectively.
