查询词典 nonionic

An attempt was made to remove color from simulated wastewaters containing Acid Scarlet GR and Reactive violet K-3R by cloud point extraction using a nonionic surfactant of Triton X-114. The influence of the concentrations, equilibrium temperature and equilibrium time on the extraction efficiency was tested. The experimental results show that the extraction efficiency to dye increases with increasing concentration of TX-114 and salt or decreasing initial dye concentration.

本文选用非离子表面活性剂TX-114作浊点萃取剂，研究了由酸性大红与活性紫构成的单元和二元混合染料模拟有色废水的萃取脱色过程，讨论了表面活性剂浓度、染料浓度、盐浓度、平衡温度、平衡时间等因素对萃取效率的影响结果表明，提高表面活性剂浓度、盐浓度有利于提高萃取效率，而染料浓度增加则使萃取效率略有下降。

It is shown from the study that influence of co-use anionic and nonionic surfactants on the enzyme activity are less than single anionic surfactant Multi-component stabilizers are much better than single-component stabilizers for enzyme activity.

研究结果表明：阴离子表面活性剂与非离子或另一种阴离子表面活性剂复配后，对酶活性的影响明显小于单一阴离子表面活性剂的影响。多组分稳定剂比单组分稳定剂对改善酶的稳定作用好得多。

Contrarily, cationic surfactant CTAB and nonionic surfactant_9 have the same effects: the two substances\' enterings cause the superficial enzymatic activity to decrease rather than the total loss in whatever the buffers. There is no Soret movements except that a longer wavelength movement by_9\'s treatment under pH5.2 buffer condition.

阳离子表活剂CTAB和非离子型表活剂9的作用结果类似：无论SBP带何种净电荷，两类物质的加入使得表观酶活力降低但不是完全失去：紫外-可见电子吸收光谱上特征Soret带位移保持不变；只是9在pH5.2缓冲液中Soret带发生红移。

The scattering spectra of this system were measured using an ordinary spectrofluorophotometer. Influence of experimental conditions, such as pH, ionic strength, and concentration of CAS, on the intensity of light-scattering was studied. Effects of surfactants (cationic, anionic, and nonionic), amino acids, and metal ions on the combination of CAS with protein were also investigated.

用普通的荧光分光光度计测量了这一体系的散射光谱，研究了pH，离子强度和试剂浓度等实验条件对散射光强的影响，考察了阳离子、阴离子和非离子表面活性剂以及氨基酸和常见金属离子对反应体系的作用。
