METHOD FOR DETERMINING TOTAL SOLUBLE SALT CONTENT IN SALINE SOIL, AND METHOD FOR EVALUATING SOIL TYPE AND SALINIZATION DEGREE OF SALINE SOIL

METHOD FOR DETERMINING TOTAL SOLUBLE SALT CONTENT IN SALINE SOIL, AND METHOD FOR EVALUATING SOIL TYPE AND SALINIZATION DEGREE OF SALINE SOIL

Provided are a method for determining a total soluble salt (TSSC) in a saline soil, and a method for evaluating a soil type and a salinization degree of a saline soil. Based on a principle for measuring a refractive index, as well as a relationship that refractive index is directly proportional to a...

description Provided are a method for determining a total soluble salt (TSSC) in a saline soil, and a method for evaluating a soil type and a salinization degree of a saline soil. Based on a principle for measuring a refractive index, as well as a relationship that refractive index is directly proportional to a solution concentration, the TSSC is rapidly determined through measured refractive index and a linear relationship between the refractive index of a saline soil leachate and the TSSC. The TSSC is quickly determined by using a portable refractometer; and contents of chloride ions and sulfate ions are quickly determined by using a portable chloride ion electrode-sensing analyzer and a portable barium ion electrode-sensing analyzer, respectively. In this way, rapid determination of TSSC and evaluation of salinization degree in the saline soil are realized at a construction site.
