text: The present invention now provides a process permitting wet-processed phosphoric acid to be freed in simple fashion by a one-step operation from heavy metal ions, especially cadmium, copper, lead and mercury ions, by contacting the phosphoric acid with an adsorbent and a diorganyldithiophosphoric acid ester, the crude wet-processed phosphoric acid being contacted either with a mixture consisting of the adsorbent and ester or, after treatment with the ester, with the adsorbent alone.
