摘要
应用Ti(Ⅳ ) -水杨基荧光酮 -溴化十六烷基三甲基铵显色体系测定了聚烯烃树脂中的钛 ,建立了测定聚烯烃树脂中钛的灵敏、快速分析方法。对测定条件、灰化条件、干扰的消除进行了考察。摩尔吸收系数为 1 62× 1 0 5L/(mol·cm) ,线性范围 0～ 2 0 μg/1 0ml,加标回收率 95 6%～ 1 0 4 0 %。方法简便、灵敏、准确。
An analytical method for sensitive,rapid determination of titanium in polyolefin resins was developed using titaniumsalicylfluoronecetyltrimethylammonium coloured system.Measuring and ashing conditions and elimination of interference were studied.The molar absorption coefficient ε535 nm is 162×105 L/(mol·cm),linear range is 0～20μg/10ml,and recoveries of standard addition are 956%～1040%
