In a traditional total quantity distillation setup or a half micro-distillation setup, the separation and absorption of ammonia and constant volume must be done separately, so the analyzing program is complex and needs long analysis time. By the rapid azotometer (Type: NC2), the ammonia in the waste water could be analyzed through one step which includes separation, absorption and titration. Compared with the tradition analysis methods, the ammonia-N in waste water can be analyzed more quickly.

含氨废水通过NC2定氮装置将氨分离，吸收，滴定集为一体，克服了传统全量蒸馏装置或半微量蒸馏装置将废水中的氨分离，吸收，定容分步进行的复杂，耗时缺点，从而达到快速测定废水中氨氮含量的目的。

The ionomer membrane under the conditions of 20℃ and 0.05 MPa shows better permeaselectivities that the permeability coefficient of CO_2 and CO_2/ N_2 separation factor are 223 Barrer and 65.70, respectively, while CO_2 / CH_4 separation factor is only 14.70. An obvious increase in P_(CO_2) with decreasing pressure difference exhibits a characteristic of facilitated CO_2 transport, which is not disappear and almost unchange after two months. There is no this behavior for N_2 and CH_4. Hence, P_(CO_2) and α_(CO_2/N_2) and α_(CO_2/CH_4) can be enhanced simultaneously.

该离聚体膜显示出良好的CO_2渗透性能，在20℃和0.05MPa压差下，CO_2渗透系数P_(CO_2)和CO_2/N_2分离系数αCO_2/N_2分别高达223 Barrer和65.70.P_(CO_2)和αCO_2/N_2随CO_2压差的降低而明显增大，显示出促进输送特征，这一行为即使在膜放置2个月之后并不消失，渗透分离性能变化不大。N_2和CH_4无此性能，因此在气体压差较低时，P_(CO_2)和αCO_2/N_2、αCO_2/CH_4可同时提高。

Results showed that the best separation factor of sulfides amounted to 1.7 by ZSM-5 membranes loaded with 0.2 mol/L Ag+ solution. The separation performance of the membranes was the best when activated 450℃. Benzothiophene showed a strong competitive adsorption effect to thiophene.

实验表明：当银离子浓度为0.2 mol/L时硫化物的分离因子最高达到1.7；当活化温度为450 ℃时ZSM-5分子筛膜的分离性能最好；苯并噻吩对噻吩有较强的竞争吸附影响。

The separation of optical isomers of 2, 2'-dihydroxy-1, 1'-binaphthyl and 2, 2'-diamino-1, 1'-binaphthyl was studied by reversed-phase high performance liquid chromatography on a chiral stationary phase consisting of-hydroxypropyl-β-cyclodextrin (Cyclobond Ⅰ 2000 SP)using methanol/water as the mobile phase. The effects of mobile phase ratio, flow rate and column temperature on separation of optical isomers of DHBN and DABN were investigated.
