[A photometric method of analysis of cyanides].

The contributors propose a selective photometric technique for detection of sodium and potassium cyanides in different washings, sewage, overalls extraction. The technique was based on the formation of a polymetyne dye, and barbituric acid and pyridine reactions. It proved efficient in detecting the cyanides within 0.01-0.054 mg/dm3, 1-100 mg/l, 0.08-1.24 mg/dm3 with deviations not exceeding 23%. Duration of the test was limited to 25-30 min.

[A method of cleaning overalls contaminated with sodium cyanide].

The contributors propose a new technique of cleaning overalls in galvanic shops from crystalline natrium cyanide (NC) and alkaline solutions. The technique includes washing in hot 0.05% syntamide-5 solution for 4-5 min., double rinsing and centrifuging. The remaining quantity of NC on washed overalls does not exceed 0.02 mg/m2 (evaluated in hydrocyanic acid). Subsequent contaminations of the overalls with NC do not entail the accumulation of NC residual content. The physical and chemical characteristics of this type of overall washing are more preferable as compared to those attained through soaking in ferric sulfate solution.
