Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard SN/T 0863-2000 "Determination of meat and meat products import and export atomic absorption spectrophotometry nickel."
This standard and SN/T 0863-2000 compared to the main technical changes are as follows.
--- Detection by the flame atomic absorption spectrometry to the graphite furnace atomic absorption spectrometry;
--- Pretreatment methods into a closed microwave digestion method.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Shanghai Entry-Exit Inspection and Quarantine Bureau.
The main drafters of this standard. Yang Kecheng, Vang Pao root, Zhou Yao, Fan Xiang, Ge Liping, Yang Zhenyu.
This standard replaces the standards previously issued as follows.
--- SN/T 0863-2000.
Determination of export meat and meat products of nickel
Atomic absorption spectrophotometry
1 Scope
This standard specifies the graphite furnace atomic exports of meat and meat products of nickel content absorption spectrophotometric method.
This standard applies to the determination of meat, luncheon meat, bacon and a sample of nickel.

Laboratory use specifications and test methods GB/T 6682 Analysis
3 Method summary
After nickel sample Microwave Digestion, dissolved in the acid solution. Solution in graphite furnace atomic absorption characteristic resonance line in a
Within a given range, the absorption is proportional to the amount of nickel content. Standard curve quantification.
4 Reagents and materials
Test water line with GB/T 6682 stipulated two of water.
4.1 Nitric acid. 65%, pure class distinctions.
4.2 nitric acid (2%). Take 2mL nitric acid (4.1), volume with water to 100mL.
4.3 Nickel standard solution. 1g/L, certified reference materials, the medium is a dilute acid solution.
4.4 Nickel standard curve solution. nickel proportionally standard solution (4.3) diluted to five levels. 10μg/L, 20μg/L, 30μg/L,
40μg/L, 50μg/L, the final medium is nitric acid (4.2). Now with this solution before use.
5. Apparatus
5.1 graphite furnace atomic absorption spectrophotometer. with a nickel hollow cathode lamps and automatic injection devices.
5.2 closed microwave digestion.
5.3 Analysis of balance. a sense of the amount of 1mg.
6 Sample Preparation and Storage
6.1 Sample Preparation
Remove all the samples taken from a representative sample of about 500g, full break, mix, are divided into two, respectively, into a clean container inside.
Seal as a sample and labeled. In the sample preparation procedure, it should prevent contamination of the sample being nickel.
