Phosphorus is an essential mineral that the body needs Hyperphosphatemia or high phosphorus levels in the body is generally caused by kidney diseaseor by consuming too much dietary phosphorus and not enough dietary calcium. Normal working kidneys help remove excess phosphorus in the blood. When a ...
3. Water treatment agent: Sodium hexametaphosphate is widely used as a water treatment agent for purifying tap water and industrial wastewater. It can react with calcium, magnesium, and other ions in water to form insoluble precipitates such as calcium phosphate and magnesium phosphate, reducing wate...
