1·The conversion of cyano group was measured indirectly by the adsorption capacity for copper of the chelating resin.
以肟型树脂对铜吸附量的大小，间接判断树脂中氰基转化率的相对大小。
2·The formation of 1, 3, 5-triazine ring by cyclotrimerization of cyano group was verified by infra-red spectroscopic analysis.
用红外光谱分析法证实了由氰基三聚环化生成了1,3,5 -三嗪环。
