Potassium Fixation in Beidellite Through Wetting and Drying

Abstract

The present study is conducted in a bid to highlight the variation noticeable in the potassium (K) exchange capacity for a K-beidellite, as a function of the number of wetting and drying (WD) cycles. The reached findings proved to reveal that the amount of fixed K+ appears to be noticeably related to both of the number of WD cycles and the negative charges arising from the substitution occurring in the octahedral sheets.
