Abstract

The performance characteristics of the argentometric method of cyanide determination was investigated using the calibration curve method. The assessment offer linearity within the range 1.7x10-3moles to 3.5x10-3moles with a sensitivity of 0.6millimoles of cyanide per dm3 of 0 .0200 moldm-3 AgNO3. It gave a detection limit of 0.7 millimoles (0.02gCN).The interference studies within the linear range shows that halides (Cl -, Br -, I -) do not interfere in the analysis when there is excess of CN - in the sample. The assessed method was applied to determine cyanide in cassava samples and pack cyaniding compositions and residues.
