Determination of lead and cadmium in soil quality and effective state Atomic Absorption Spectrometry1 ScopeThis standard specifies the soil available lead and cadmium in atomic absorption spectrometric method. This standard applies to soil available Pb and Cd determination. Soil AVAILABLE LEAD apply to flame atomic absorption spectrophotometry; Soil available Cd content of 0.5mg/kg or more suitable for flame atomic absorption spectrophotometry; soil available Cd content 0.5mg/kg The following applies to graphite furnace atomic absorption spectrophotometry. Principle 2 With DTPA (diethylenetriaminepentaacetic acid) extraction agent leached lead and cadmium in the soil, and crop the content of lead and cadmium have a higher absorption Correlation. DTPA can quickly generate a water-soluble compound of lead, cadmium and other ions in a special hollow cathode lamp illumination, gaseous gold in the ground state Metal atom absorption of a specific wavelength and the transition to a higher energy state level, the greater the number of atoms in the ground state optical path, characterized by its radiant energy Greater absorption and is proportional to the density of the atoms, and finally not be quantified according to the standard series.3 Reagents......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23739-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 23739-2009_English as soon as possible, and keep you informed of the progress.
