titrations b) involve an oxidant-sensitive indicator or enjoy hobby essay reactant (e.g., methylene blue or c) involve biological organisms or products which are affected by oxidants (e.g., bioassays). The mechanism of removal is catalytic decomposition of the H2O2 to oxygen and water. We specialize in turn-key solutions for municipal wastewater and drinking water treatment; refinery, gas, oil and petrochemical applications; industrial wastewater and air quality treatment; remediation; and UV-Oxidation. Bisulfite (or sulfite) reacts quickly to remove residual H2O2, as it does with other oxidants. The rate of H2O2 decomposition (to oxygen and water) increases several fold as pH increases and temperature rises.

For treated samples of industrial waste containing several hundred mg/L H2O2, it may be possible to raise the pH to 10-11 and the temperature to 40-50 deg-C and allow the sample to sit overnight. We have capabilities to include ICP, ICP/MS, GC, GC/MS, IC, spme to name a few. More and more municipalities are testing how to write proposal in latex for algal toxins in there surface water. H2O2 2OH- O2 H2O 2e- (-0.146 mV). Carbons which perform best are either catalytically-active (e.g., Calgon's CentaurTM Carbon) or impregnated with catalytically-active metals such as copper, chrome, or silver. This is the more versatile procedure because of its high selectivity to H2O2. The amount of enzyme added depends on its activity and the time permitted before analysis - you should consult the label for this information.
