  • Chloride Determination in Copper-Sulfuric Acid Plating Bath
    Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor. Consult manual for millivolt measurement instructions. If the electrode is being used for the first time, please follow
  • Determination of Ionized Calcium in Skim Milk
    Ionized calcium in skim milk can be measured directly in the normal range (1 mM to 4 mM) utilizing the Iotron Calcium Electrode. Potassium Chloride is added to both standard and sample for consistent ionic strength. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV
  • Chloride Analysis in Water
    and swamp waters. Sulfide is easily removed by aeration. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor. Consult manual for millivolt measurement instructions.
  • Bromide Analysis in Nickel Sulfamate Bath
    may be present in trace amounts. As bromide concentrations may vary widely, use the following method as a general guide line. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor
  • Bromide Analysis in Water
    The following analysis is valid for bromide levels as low as 0.5 ppm. Check the deionized water used in reagent preparation. The specific conductivity should be no greater than 2.0 uSCM-1 (5 Mohms). Sample solutions should be free of iodide and sulfide ions. Equipment: Meter: pH/Millivolt meter
  • Advanced Oxidation Ditch Performance (.pdf)
    that is available to the biomass. If cell tissue is the primary carbon source (endogenous respiration), the denitrification rate will be relatively low. If raw sewage is the primary carbon source, the denitrification rate will be substantially higher (typically 6 to 10 times higher). The optimum pH
