TOTAL NITROGEN AND PHOSPHORUS ESTIMATION REACTOR MODEL NO.- ACM- TRES-55609
Weiber's Multi function reactor is an ideal instrument for performing multiple functions as ascertaining Chemical Oxygen Demand, i.e. COD and TP / TN. COD is necessary to ascertain the oxygen requirement of waste water prior to its release into the environment, so that it can be monitored and controlled to avoid harmful effects on the nature, human beings, etc. Chemicals / Nutrients as Nitrogen and Phosphorous are vital water quality parameter. Depending upon their chemical forms they significantly directly or indirectly affect plant growth, oxygen concentrations, water clarity, etc. Plants require these chemicals to grow, reproduce and to keep away diseases. Natural sources of N include fresh water, decomposing organic matter and waste, extraction of nitrogen gas from some bacteria and blue algae. Man made sources are effluent from water treatment plants, agricultural fertilizers, industrial wastes, livestock wastes, etc. Phosphorous exists in water in several forms; total phosphorous is one of them. Decomposition of dead plants and animals adds to TP in water. These can enter an estuary from water treatment plants, sewage, soils, agricultural fields, etc. High P level is there due to storms, or due to irrigational activities. Due to atmospheric deposition the N and P pollutants from manmade sources in the air fall on land or water bodies, thereby contaminating them. An alkaline persulfate digestion converts all forms of nitrogen to nitrate. Nitrate then reacts with chromotropic acid under strongly acidic conditions to form a yellow complex with an absorbance maximum at 420 nm. Working Principle for TP: Phosphates are converted to orthophosphates by heating with acid and persulfate. Orthophosphate reacts with molybdate in an acid medium to produce a mixed phosphate/molybdate complex. Ascorbic acid then reduces the complex, giving an intense molybdenum blue color. Test results are measured at 610 nm. TECHNOCRACY PVT. LTD.
