| titleOfInvention | The detection method of biologically effective state cadmium in a kind of soil |
| abstract | The detection method of biologically effective state cadmium in a kind of soil includes the following steps: the acquisition of S100 sample and pretreatment, and acquisition soil simultaneously air-dries the soil of acquisition at room temperature, and 200 meshes are crossed after grinding, pedotheque is made；1-5g pedotheque is weighed to be placed in 250mL polytetrafluoroethylene (PTFE) Centrifuge Cup, it is separately added into the ethanol solution 25mL of 1mol/L ammonium chloride solution 25mL and 80%, is cleaned using ultrasonic cleaning machine, then be centrifuged through centrifuge, extracting solution is made after taking supernatant liquid filtering film, the HNO for being 1% with concentration 3 Solution constant volume；S200 measures the concentration of biologically effective state cadmium in extracting solution, and the standard curve for measuring the various concentration of biologically effective state cadmium is established by inductively coupled plasma mass spectrometry using icp ms；The concentration of biologically effective state cadmium in extracting solution is measured by standard curve using icp ms；S300 interpretation of result calculates the content of biologically effective state cadmium in the pedotheque of measurement according to the quality of the pedotheque of measurement and the concentration of the extracting solution of measurement. |
