    Determination of zinc in water by fluorimetric method

    In accordance with WHO’s Guidelines for Drinking Water Quality there is no health-based guideline value of zinc in water concentration. Concentration of zinc in tap water can increase as a result of its dissolution from pipes. Also, elevated levels of zinc may be an indicator of increased concentrations of other toxic metals; thereby zinc in water analysis is an essential analytical task. Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of zinc in...

  • Cyanide Treatment with Hydrogen Peroxide

    Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination. However, chlorination of cyanide results in highly toxic intermediates (e.g., cyanogen chloride) and, if organic material is present, chlorinated VOC’s. These compounds, together with the residual chlorine,...
