1932 I. M. Kolthoff in Jrnl. Physical Chem. 36 861 First of all, calcium oxalate precipitates and then on standing magnesium oxalate crystallizes out slowly. Therefore, we are not dealing here with a case of coprecipitation, but of post-precipitation, the crystals of calcium oxalate being not at all or only slightly contaminated by magnesium.

1963 G. Svehla tr. L. Erdey Gravimetr. Anal. i. iii. 183 Tin (IV) sulphide tends to carry down nickel, cobalt and iron ions from a hydrochloric acid containing solution by post-precipitation.

1998 Ecology 79 2367/1 LH levels were measured using a postprecipitation, double-antibody radioimmunoassay.
