Chemical extraction of potassium from soils and micaceous minerals with solutions containing sodium tetraphenylboron; 4, Muscovite


, : Chemical extraction of potassium from soils and micaceous minerals with solutions containing sodium tetraphenylboron; 4, Muscovite. Proceedings - Soil Science Society of America 30(2): 185-188

The samples were placed in NaCl-BaTPB solutions at 25 degrees C, and the precipitated K was separated with boiling NH (sub 4) Cl solution that contained HgCl (sub 2) . With this method 96 percent of the K was removed in <10mu muscovite in 16 weeks. This was the maximum amount that was extracted.
