GB/T 11899-1989 《Water quality--Determination of sulfate--Gravimetric method》 Related products

GB/T 11899-1989 is a water quality testing standard. The weight method is used to determine the sulfate content in water. Sulfate is widely found in all kinds of water bodies, and its content affects the water quality. If it is too high, it will lead to problems such as bitter taste of water and corrosion of equipment. The standard specifies the whole process from water sample pretreatment, settling sulfate, to settling filtrate, drying, and weighing to calculate the sulfate content. The weight method is cumbersome but accurate in operation. It is suitable for a variety of water samples. It provides reliable data support for water quality monitoring, industrial water use assessment and related research, and helps to ensure high-quality water use.
