The adsorption capacity and adsorption efficiency of the fiber to Cr(VI) ions and Cu(II) ions are calculated by formulas (1), (2) and (3) respectively22–24.

In the formula: qe represents the equilibrium adsorption capacity of Cu(II) and Cr(VI) (mg·g−1); qt represents Adsorption amount of Cu(II) and Cr(VI) at time t (mg·g−1); Et represents adsorption efficiency at time t (%); V represents Solution volume (mL); Co represents the mass concentration of Cu(II) and Cr(VI) in the solution before adsorption (mg·L−1); Ce represents the mass concentration of Cu(II) and Cr(VI) in the solution at the time of adsorption equilibrium (mg·L−1); Ct represents the mass concentration of Cu(II) and Cr(VI) in the solution at time t (mg·L−1); M represents dry weight of CS fiber (g).
