Summary
Experimental Factors Estimation in Nephelometric Procedures
The nephelometric determinations of low concentrations of sulphate ions are usually influenced by a variety of experimental factors such as presence of stabilizing agents, acids, interferences, equilibration and stirring time etc. The present study makes an attempt to estimate the weight of 6 input factors at different levels of sulphate concentrations by the use of the economic experimental design known as random balance method. It is found that some of the input factors (presence of stabilizing media, acidity) are of higher rank than others (equilibration time or barium ions concentration). Using these results it is easy to find optimal conditions for micro-determination of sulphates by nephelometry.
