| 摘 要： | 对总离子强度缓冲剂对含氟溶液测定的影响进行了研究,结果表明:加入TISAB时测定的吸附平衡液浓度比未加入时高,且初始浓度的越大其差值越大,说明未加入TISAB时并未能测出吸附平衡液中的总氟,而是有一部分未被测出。未被测出的浓度是紫色土>红壤>黄壤、石灰土,低浓度条件下石灰土大于黄壤,而较高浓度条件下黄壤大于石灰土。加入TISAB与不加入TISAB时吸附量相差很大,加入情况下吸附量要小。在氟的吸附试验中,应加入离子强度缓冲剂(TISAB),以测定出平衡液中的总氟。 |

| Abstract: | The measarement of fluorine liquid as influenced by TISAB was studied. Adsorption liquid fluorine concentration with adding TISAB was higher than that of no addition, and the difference was bigger with the increase of oriental concentration. This indicated that total fluorine in liquid can't be entirely tested without adding TISAB. Untested fluorine concentration in soils is in the order purple soil>red soil>yellow soil and calcareous soil. The difference of adsorption contents was big between adding TISAB and not. The TISAB should be added to test the total fluorine of adsorption liquid in the study of fluorine adsorption. |
