BAIJIAN - a professional third-party testing and inspection platform that provides relevant testing and inspection services such as surface water, gro
The determination of water quality and turbidity has been carried out using a turbidimeter method. Warning: The sulfuric acid used in the experiment is toxic and carcinogenic. The reagent preparation process should be carried out in a fume hood. Protective equipment should be worn as required during operation to avoid contact with skin and clothing. 1. Scope of application: This standard specifies the turbidimeter method for measuring turbidity in water. This standard is applicable to the determination of turbidity in surface water, groundwater, and seawater. The detection limit of the method is 0.3 NTU. 2 Normative References: This standard references the following documents or their clauses. For undated references, their valid versions are applicable to this standard. GB 17378.3 Marine Monitoring Specification: Part 3: Sample Collection, Storage and Transportation HJT91 Technical Specification for Surface Water and Sewage Monitoring HJ/T 164 Technical Specification for Groundwater Environment Monitoring 3 Terminology and Definitions 3.1 Turbidity, also known as turbidity. It is a measure of the decrease in liquid transparency caused by the presence of substances in water that have a scattering effect on light. Suspended and colloidal particles in water will scatter and absorb light passing through the sample, and the scattering phenomenon of light produces turbidity. The scattering characteristics of light by particulate matter in the sample are used to characterize turbidity, and the measurement unit is NTU (NcphelometricTurbidity Units)
