中文摘要：
以3．0mol／LHNO3活化后的三钛酸钠晶须为吸附剂，以电感耦合等离子体原子发射光谱（ICP—AES）法为检测手段，探讨了静态条件下三钛酸钠晶须对Cu（Ⅱ），Co（Ⅱ），Pb（Ⅱ）的吸附和解脱行为，考察了影响其吸附和解脱的主要因素、三钛酸钠晶须对Cu（Ⅱ），Co（Ⅱ），Pb（Ⅱ）的吸附等温线及三钛酸钠晶须对其它几种离子吸附的情况。结果表明：在pH5．0下，0．2500g的三钛酸钠晶须对上述3种离子的吸附效果最好；在沸水浴中，以10mL3．0mol／L的HCl作解脱剂，可实现3种离子的定量解脱；将其用于水样测定，加标回收率在91％到102％间。
英文摘要：
In a static system, through taking sodium trititanate whisker previously activated by 3.0 mol/L HNO3 as the solid sorbent for the enrichment/separation of trace amounts of Co（Ⅱ）,Cu（Ⅱ）,Pb（Ⅱ） ions,the adsorption and elution behaviors of the sorbent to Co（Ⅱ）, Cu（Ⅱ）, Pb（Ⅱ） have been investigated by inductively coupled plasma atomic emission spectrometry. The main factors such as pH, amount of sorbent, eluent and elution temperature affecting the adsorption and elution of Co（Ⅱ）,Cu（Ⅱ）,Pb（Ⅱ）,the adsorption isotherms of Co（Ⅱ）,Cu（Ⅱ）,Pb（Ⅱ） and the adsorption behavior of the sorbent to some other ions are comprised in the study. By analyzing the experimental results, using 0. 250 0 g of sorbent can get the highest absorptive rate for Co（Ⅱ）, Cu（Ⅱ）, Pb（Ⅱ） in a buffer solution at pH 5.6 and using 10 mL of 3.0 mol/L HCl as the eluent can realize quantitative elution of Co（Ⅱ）, Cu（Ⅱ）, and Pb（Ⅱ） in the boiling water bath. The sorbent has been applied to the determination of Co（Ⅱ）, Cu（Ⅱ）and Pb（Ⅱ） in the nature water with addition standard recoveris of 91%-102%.
