壳聚糖与环硫氯丙烷反应合成了一系列含S和N的交联型螫合树脂。这类树脂对贵金属离子如:金、银、钯、铂等具有优良的吸附性能。

In this paper syntheses and adsorption properties of some chelating resins which contain S and N

obtained by the reaction of chitonsan with chloromethylthiirane (I) were described. Crosslinking of chitosan by(I) at (I)/NH2 molar ratios of 0.5

1.0

2.0

5.0 and 10.0 gave resins from PCS 1 to PCS 5

the S-content in resins increased with increasing of quanity of (I) used

while the N-content decreased.Within the series of PCS

the more the content of S% in the resins

the higher the adsorption capacities for noble metal ions. The capacities of PCS 5(m mol/g)for Ag(I)

Au(III)

Pd(II) and Pt(IV) were 4.46

4.86

3.14 and 1.87 respectively. The adsorption percentage andselectivity of PCS 5 for the noble metals were also determined.
