Abstract
Pink coloured stable gold sol (lambda(max): 523 nm) has been prepared photo chemically in aqueous Triton X-100 (TX-100) medium and used for spectrophot ometric determination of cyanide. The colour of the sol decreases on cyanid e addition and becomes colourless at the end point. Linear calibration is o btained in the range of 0-26 ppm of cyanide concentration. The relative sta ndard deviation for 8.65 ppm of cyanide is found to be +/-2.03%. The method is simple, rapid and applied for real sample analysis.
