SOP FOR Determination of pH Principle Electrometric Method The pH value is determined by measuring the electromotive force of a cell that is comprised of a test solution-immersed indicator electrode (a hydrogen-ion-responsive electrode, such as a glass electrode) and a reference electrode (typically a mercury/calomel electrode), which is contacted with the test solution through a…
SOP for the determination of Turbidity Principle This method is based on comparison of the intensity of light scattered by the sample under defined conditions with the intensity of light scattered by a standard reference suspension under the same conditions. The higher the intensity of scattered light the higher the turbidity. Formazin polymer is used…
SOP For Determination of Temperature Principle Temperature measurements may be made with any mercury-in-glass thermometer provided it is checked occasionally against a precision thermometer certified by a competent agency. Apparatus Beaker Calibrated thermometer Procedure Calculation Take 3 reading and Result given after calculation of Mean of thermometer temperature reading. Safety Guideline Proper safety & health…
SOP FOR DETERMINATION OF COLOR IN WATER METHOD : SINGLE WAVWLENGTH BY SPECTROPHOTOMETRIC Principle Colour is determined spectrophotometrically at a wavelength between 450 and 465 nm, with platinum cobalt solutions as standards. True colour of samples and platinum cobalt standards follow Beer’s Law. Interferences The primary interference is from colloidal suspended particles that scatter light…
1.0 Cleaning of sample Container 2.0 Sample Volume A two-litre sample is normally sufficient for most physical and chemical analysis. However, the quantity may be varied depending upon the type of analysis, methods used etc. 3.0 Sample Preservation Waste waters usually decompose rapidly at room temperature, therefore, certain tests. Namely, dissolved oxygen, sulphides, residual chlorine,…

Water testing is an essential aspect of ensuring the safety and quality of water used in chemical industries. Water is often used in various industrial processes in chemical industries, and it is crucial to ensure that it is free from contaminants and impurities that can affect the quality of the final products, the efficiency of…
ASH FUSION TEMERATURE What Is ASH FUSION TEMPERATURE ? Ash Fusion Temperature (AFT) is an important property of coal, which is the temperature at which the ash residue from burning coal starts to soften and fuse together. The AFT is typically determined by heating a sample of coal in a high-temperature furnace, and observing the…
