摘　　要：The N alkyl chitosans were prepared from chitosan through Schiff base formation and hydrogenation. The adsorption properties of N alkyl chitosans, bearing the same substitution degree but different carbon chain length and vice versa for Cu(Ⅱ), Hg(Ⅱ) and Pb(Ⅱ) have been investigated. It is found that chitosan derivatives of the same carbon chain length show the highest adsorption capacity for tested ions, when their substitution degree is ranged in 0 35～0 39. And among the chitosan derivatives bearing the same substitution degree, N pentyl chitosan shows the highest adsorption capacity towards mentioned ions.The N alkyl chitosans were prepared from chitosan through Schiff base formation and hydrogenation.
