Scope

GB/T 14506.18-2010 is the English-translated version of 硅酸盐岩石化学分析方法 第18部分:铜量测定.

GB/T 14506.18-2010 specifies methods for determining the copper content of silicate rocks, and applies equally to soils and stream sediments.

It gives an ammonia-ammonium chloride supporting electrolyte polarographic method (copper above 4 µg/g with a square-wave polarograph, above 10 µg/g in the derivative mode of an oscillopolarograph), a potassium thiocyanate-ethylenediamine-sodium sulfite supporting electrolyte catalytic polarographic method for 5 µg/g to 125 µg/g, and flame atomic absorption spectrophotometry for 5 µg/g to 500 µg/g.

For the polarographic methods the test portion is decomposed in PTFE with hydrochloric, nitric, hydrofluoric and perchloric acids, and each method sets out reagents and standard solutions, apparatus with the mercury-handling warning, sample preparation, blank and verification tests, calibration series, calculation and precision data (for the first method r = 0.434m^0.75 and R = 2.399 + 0.242m, from seven laboratories).

It replaces GB/T 14506.18-1993, adding normative references and safety warnings. Issued on 10 November 2010, in force since 1 February 2011. Classification: ICS 73.080, CCS D53. The document runs to 12 pages, delivered complete in English translation.
