    Adsorption of amino acids

    The author and members of the research team studied the adsorption properties of amidoxime-based chelating spherical lignin adsorbents for L-lysine , L-arginine and L-histidine , as listed in Table 4-54


    Table 4-54 The effect of static adsorption of amino acids:


    Before basic amino acids are adsorbed, the pH value is usually adjusted to a certain value with hydrochloric acid, ammonia or sodium hydroxide .


    Table 4-55 The influence of different concentrations of NaCl and NH 4 CI on the equilibrium adsorption capacity


    It can be clearly seen from Table 4-55 that as the concentration of sodium chloride increases, the adsorption capacity of each amino acid decreases rapidly, and the effect of ammonium chloride is more pronounced than that of sodium chloride


    Use 2.


    Table 4-56 Repeated use effect of spherical lignin adsorbent


    The author and members of the research team also studied the adsorption kinetics and thermodynamics of L-aspartic acid by the spherical lignin adsorbent prepared by epichlorohydrin cross-linking through static adsorption experiments, and discussed the effect of pH on the adsorption process.
