  1. The fixed Cs (fxCs) amount and exchangeable Cs (exCs) solubilization ratio were referred to Eqs. 4 and 5. The numbers in parentheses indicated the exCs solubilization ratio and its standard deviation. *Total value did not match due to the rounding of values. The same letters indicated the comparison groups and there was no significant difference between them according to t-test
