1 Scope

GB/T 14506.32-2019 is the Chinese national standard on methods for chemical analysis of silicate rocks - part 32: determination of 20 components including aluminium oxide etc. - mixed acid digestion-inductively coupled plasma atomic emission spectrometry, in the field of mining and minerals. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 18 October 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2020. Classification: ICS 73.080, CCS D53. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This part of GB/T 14506 specifies the determination of three in silicate rock by mixed acid decomposition-inductively coupled plasma atomic emission spectrometry Aluminum oxide, calcium oxide, total iron (calculated as ferric oxide), potassium oxide, magnesium oxide, manganese oxide, sodium oxide, phosphorus pentoxide, titanium dioxide, antimony, Amounts of antimony, cobalt, copper, lithium, nickel, lead, antimony, bismuth, vanadium and zinc. This section applies to silicate rock in aluminum oxide, calcium oxide, total iron (calculated as ferric oxide), potassium oxide, magnesium oxide, manganese oxide, Mixed acid decomposition-inductively coupled isotope of sodium oxide, phosphorus pentoxide, titanium dioxide, antimony, bismuth, cobalt, copper, lithium, nickel, lead, antimony, bismuth, vanadium and zinc Determination by atomic atomic emission spectrometry is also applicable to the determination of the above components in soil and sediment samples. The method detection limits and measurement ranges are shown in Table 1. Table
