Table 1 Theoretical calculation of the substance content in reaction 5 when it reached equilibrium at different initial His/Co²⁺ (T = 24 °C, pH = 7, initial cobalt(II) = 5 mM)

His/Co²⁺	Co(II)His/initial cobalt(II) (%)	Residual Co²⁺(mg/L)	Residual His (mM)
2	93.833	18.194	0.6
3	99.900	0.294	5
4	99.975	0.074	10
5	99.989	0.033	15
6	99.994	0.018	20

The equilibrium constant under 30 °C was not publicly available, thus the constant was referred from 24 °C
