Question

Write a short note on turbidometer.

Answer 1

Principle and Theory of Nephelometry and Turbidimetry:

The principle of nephelometry and turbidimetry is based on the scattering or absorption of light by solid or colloidal particles suspended in solution. When light is passed through the suspension, part of incident radiant energy is dissipated by absorption, reflection, and reaction while remainder is transmitted.

In fact the measurement of the intensity of transmitted light is a function of the concentration of dispersed phase and this becomes the basis of turbid metric analysis.
