potassium removal from micas

Potassium an overview ScienceDirect Topics

With the potassium ferrate dosage concentration 10 mg/L, the amount of COD removed theoretically was 1.21 mg/L, but the removal of COD in the experiment process was 2022 mg/L, which was 1671 times as much as the theory. This may be that after potassium ferrate was dissolved in leachate, the Fe(VI) did not translate directly to Fe(III) in the decomposition process.

How to Reduce Potassium Levels in Soil Hunker

A bit too much potassium in garden soil is not typically a problem for most plants, but in high excess, potassium can cause problems. One major problem is the inhibition of calcium. Common causes of exorbitant potassium levels include overfertilizing and a large number of rocks and minerals in the soil.

Effects of potassium removal on the bdimension of phlogopite.

K was removed from 520 µ size fractions of 2 phlogopites by sodium tetraphenylboron treatment and was replaced with various exchange ions. The bdimension of the mica increased with K+ removal, which suggested that the K+ ion in phlogopite acts to constrain b. The KO bond in phlogopite must be lengthened and weakened relative to the bond in dioctahedral micas.
