Heavy metal salt precipitation: Because of its positive charge, it can be combined with protein negative ions to form insoluble protein salt precipitation. When the solution pH is above protein and other electrical points, heavy metal salt (such as PB2 , CU2 , HG2 , AG , etc.) is easily combined with protein Involved salt and precipitation.
