摘要
提出了以硅胶为载体将五价锑酸浸渍在活化硅胶中作为交换柱滤料,以除去矿泉水中钠离子,脱钠率可达99％以上,脱钠剂可再生,再生液为1mol·L^(-1)HNO_3+1mol·L^(-1)NH_4NO_3,钠离子含量的测定方法采用离子选择电极Rittner和Ma法,结果表明:此方法简便、可靠,结果满意,值得推广。
The deals with the removal of Na+ from natural mineral water by immersion on polyantimonic (Ⅴ) acid supported on silica gel is developed. Removing Na+ efficiency of adsorbent is more than 99%. 1 mol/L HNO3+1 mol/L NH4NO3 is used as regeneration solution. ion selective electrode method of 'Rittner and Ma' is applied to determine the amount of Na+. This method has been shown to be simple and reliable, the results are satisfactory.
