Spectrophotometric Analysis Of Water

Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.

Spectrophotometric analysis of water.

Spectrophotometry uses photometers known as spectrophotometers that can measure the intensity of a light beam at different wavelengths although spectrophotometry is most commonly applied to. Spectrophotometric analysis and to examine the effect of an interfering substance. 2 0 theory the first portion of a spectrophotometric analysis consists of preparing six standard solutions each with a known phosphate. The inorganic analyte being considered in this particular analysis is phosphate and the interfering substance is arsenic.

This is because water is an extremely strong nir absorber at its two absorption wavelengths of 1 940 and 1 430 nm. Before doing a spectrophotometric analysis turn on the machine so that it can warm up for 15 minutes prior to running samples. N 2 n 2 water n 2 equilibrium. The potential for human errors is minimized.

In order to apply uv visible spectrophotometric techniques for water and wastewater analyses correctly and reliably an understanding of the principles behind the technique is needed as well as guidance in best operational laboratory practices in order to obtain reliable spectral data. Used together with tntplus test kits testing steps are reduced. No 3 was. Spectrophotometry can help in determining oil and grease contamination in large water sources as well offering the ability to detect minute traces of iron in drinking water supplies.

Spectrophotometric process analysis. Spectrophotometry is widely used for quantitative analysis in various areas e g chemistry physics biology biochemistry material and chemical engineering clinical applications industrial applications etc. Also no other common material absorb strongly at the 1 940 nm wavelength making it easy for nir techniques to distinguish water from the other constituents of the sample. Water analysis made simple.

We would like to show you a description here but the site won t allow us. Nh 4 was measured by nessler s reagent spectrophotometry method crosby 1968. Spectrophotometry is a measurement of how much a chemical substance absorbs or transmits. Meanwhile pipe your sample substance into one cuvette and a control solution like water into another.

The dr3900 spectrophotometer provides the simplest way to perform tests for water analysis.
