摘要: 利用辐射方法制备硫酸根离子选择电极活性材料,至今未见报导,我们首次采用辐射接枝方法制备了以疏水性高分子为骨架的带有SO~-活性基团的功能高分子活性材料,研制了硫酸根离子选择电极。结果表明,该电极具有内阻低,响应快,稳定性较好的特点,且其功能曲线的线性范围为10~(-1)～10~(-4)MSO_4~-,适宜的pH范围为4～9。Abstract: The functional polymer active materials containing SO_4~= active group have been prepared by radiation grafting reaction, which have not reported in the literature yet. The SO_4~= ion selctive electrode was prepared. The experimental results show that the
