Method for fast obtaining mineralization degree, Na<+> and Cl<-> in coastal reclamation area mudflat surface water

Abstract

The invention discloses a method for fast obtaining mineralization degree, Na<+> and Cl<-> in a coastal reclamation area mudflat surface water. The method comprises the following steps of 1, determining the EC value x of the coastal reclamation area mudflat surface water; 2, substituting the surface water EC value x determined in the first step into a surface water mineralization degree determination formula; calculating the surface water mineralization degree y1; repeating the step; calculating the Na<+> and Cl<-> contents of the surface water; 3, judging the affiliated interval of the mineralization degree according to the surface water mineralization degree y1, the Na<+> content y2 and the Cl<-> content y3 calculated in the second step; 4, judging the surface water quality type according to the affiliated interval of the surface water mineralization degree; further judging whether the surface water is suitable for plant irrigation or not. The method provided by the invention meets the requirements of mineralization degree and Na<+> and Cl<-> dynamic monitoring during the municipal administration, civil engineering and greening building of coastal reclamation area mudflat.

Description

technical field [0001] The invention belongs to the field of ecology, and in particular relates to a method for quickly obtaining the salinity, Na+ and Cl- of tidal flat surface water in coastal reclamation areas. Background technique [0002] The basic method for the determination of the salinity of surface water and the sodium ions and chloride ions that are harmful to plants is: collect surface water samples on site, pre-treat the samples in the laboratory, use conductivity meters, drying ovens, analytical balances, and flame photometry Meter, automatic potentiometric titrator and other series of instruments and equipment, the mass method is used to measure the salinity, the flame photometer is used to measure the sodium ion, and the silver nitrate titration is used to measure the chloride ion, in order to obtain the salinity, sodium ion and chloride ion content, the whole process takes at least 6 days, which is a basic step in scientific research. Although the obtained d...
