| 1 | Alkalinity is determined by titration method and the concentration of sulfide is determined by methylene blue method. | |
| 2 | The concentration of total alkalinity was high in the near surface layer of the shelf area and the shelf break area. | |
| 3 | Experiment results show that the resin adsorption(capability) decrease with solution alkalinity increasing. | |
| 4 | In addition to its atmosphere, the temperature and alkalinity of the Earth's surface also exhibits a queer level. | |
| 5 | At sufficiently high temperatures and alkalinity, fatty esters may be hydrolyzed to produce soaps . |
