This section applies to the determination of copper content of silicate rocks, is also suitable for the determination of copper content in soil and stream sediments. Measurement range. sodium hydroxide - ammonium chloride electrode method using a square wave spectrometer is 4μg/g or more of the amount of copper. With oscillopolarography derivative unit Points was determined to 10μg/g or more of the amount of copper. SCN - ethylenediamine - sodium sulfite Polarographic determination of 5μg/g ~ 125μg/g of copper the amount. Flame atomic absorption spectrophotometry was 5μg/g ~ 500μg/g of copper content.2 Normative referencesThe following documents contain provisions which, through reference GB/T 14506 in this section constitute provisions of this section.

Weigh 67g of ammonium chloride and 12.5g anhydrous sodium sulfite, placed in 600mL beaker, approximately 150mL of water was added, dissolved, was added 262mL sodium hydroxide solution (ρ0.88g/mL), diluted with water to 500mL, stir well. Plastic bottle into a dry spare. 3.2.9 iron solution. Weigh 1.0g spectroscopically pure ferric oxide, placed in 150mL beaker, add 5mL hydrochloric acid (3.2.1), heating dissolved Once extracted, the water moved into 100mL volumetric flask, and dilute to the mark.
