DOWEX(R) 50 WX8 - Physico-chemical Properties
| Molecular Formula | N/A |
| Water Solubility | Insoluble in water. |
| Appearance | Moist Spheres |
| Color | Beige to tan or green-tan |
| Storage Condition | Sealed in dry,Room Temperature |
| Use | Soil temperature is also called cation exchange resin. Ion exchange resins containing acidic groups in the molecule (see ion exchange resins). It can swell in water or in polar solvents. The aqueous solution is acidic and can be exchanged with the cations in the solution by its hydrogen ions or potassium and sodium ions. According to the ionization constant of acidic active group, it can be divided into three categories: strong acid, medium acid and weak acid. The strongly acidic cation exchange resin contains a sulfonic acid group-SO3H, and the moderately acidic cation exchange resin contains a phosphoric acid group-H2PO4 or a phosphonic acid group-H2PO3. The weakly acidic cation exchange resin contains carboxyl-COOH or phenolic hydroxyl groups. H on these active groups can interact with the cation exchange of the test solution to achieve the purposes of purification, separation, purification, and removal of interference. |

DOWEX(R) 50 WX8 - Effect of soil temperature on plant growth and its mechanism
from VIP Journal Professional Edition
Author:

Abstract:
The Effect of soil temperature on the growth and development of the biennial herbaceous flower black heart chrysanthemum was studied. The results showed that the wet weight and dry weight of the aerial parts of heated plants were larger than those of unheated plants, while the wet weight and dry weight of the roots of heated plants were smaller than those of unheated plants; and the heating strain has a smaller root shoot ratio. These indicate that the suitable soil temperature enhances the absorption activity of the root system, which is beneficial to the growth and development of the plant above ground. At the same time, the plant root system will make an adaptive response to the bad soil temperature through the function compensation, in order to reduce the harm of bad soil temperature to plants.

DOWEX(R) 50 WX8 - Soil system classification-determination of mean soil temperature in middle age
from VIP Journal Professional Edition
Author:
Abstract:
The annual average temperature in Guangxi has a three-dimensional distribution law. The annual average temperature in some places can be estimated by a ternary empirical equation. The empirical equation is:(?) (Annual average temperature ℃)= 69.2362-0.6675 × latitude -0.2941 × longitude -0.0049 × elevation (m). With the relevant data of each meteorological station, through the linear regression equation, the additional constant of the annual average soil temperature can be obtained, and the annual average soil temperature of any sampling point can be estimated, which is convenient for field work.
