Monitoring of Ni2+ (2 mM) binding to three different substrates, CM-cellulose, α-chitin and Avicel (a), and correlation of Ni2+ cations reduced by carboxyl groups of CM-cellulose (50% substitution), the changes of absorbance were obtained by the values as read minus the background at 0 mM of carboxyl groups (b). Error bars represent SD from a total of three independent measurements
