Table 2 Theoretical calculation of the substance content in reaction 5 when it reached equilibrium at different initial cobalt concentrations (T = 24 °C, pH = 7, His/Co²⁺ = 4)

Initial cobalt(II) (mM)	Co(II)His/initial cobalt(II) (%)	Residual Co²⁺(mg/L)	Residual His (mM)
4	99.961	0.092	8
5	99.975	0.074	10
8	99.990	0.046	16
10	99.994	0.037	20
12	99.996	0.031	24
15	99.997	0.025	30
16	99.998	0.023	32
20	99.998	0.018	40

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