The maximum fixation of K occurs
Answer & Solution
Correct Answer:
Option
D
The maximum fixation of K occurs in 2 : 1 type clay minerals.
The major minerals responsible for K fixation are illite, vermiculite and smectite. It has been demonstrated that vermiculite and smectite minerals have more ability to fix K compared to other 2 : 1 minerals due to the higher specific surface area and negative layered charge.
