<p>An improved method for the quantitative analysis of total cyanide in effluent from industrial processes. Surfactant-free tubing is used in the ultraviolet digestor to avoid the use of wetting agents that interfere with test results. Titanium (IV) oxide is added to the test reagents, allowing use of the preferred low wattage, long wave length ultraviolet light, achieving improved precision and speed, without inaccuracy resulting from interference from thiocyanate.</p> |
