How can an accurate value of Ca in a cobalt sulfate solution be determined? Some people use the standard curve method, while others use the standard addition method; however, the standard addition method sometimes yields negative values. Why is that? It’s theoretically impossible for a negative value to appear; can measurements still be continued in such a situation?

Sulfate has a significant impact on macromolecular calcium; it is recommended to add a sulfate ion masking agent, lanthanum oxide, to mask it

Our factory uses atomic absorption for this purpose.

Add lanthanum chloride, using the standard curve method
