2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
Analysis of laboratory water specifications and test methods GB/T 6682-2008
3 principle
The tributyltin and triphenyltin in the sample were extracted by Soxhlet extraction with methanol as solvent. The extract was filtered and derivatized.
Phase chromatography - mass spectrometry for separation and determination, external standard method quantitative.
4 Reagent or material
Unless otherwise stated, use only analytical pure reagents and tertiary water in accordance with GB/T 6682-2008.
4.1 methanol. pure chromatography.
4.2 n-hexane. pure chromatography.
4.3 Sodium tetraethylborate.
4.4 anhydrous sodium acetate.
4.5 glacial acetic acid.
4.6 anhydrous sodium sulfate. 650 ℃ before burning 4h, stored in the dryer in the spare.
4.7 Tributyltin chloride Purity. ≥98%.
4.8 Triphenyltin chloride Purity. ≥98%.
4.9 2% sodium tetraethylborate solution. Weigh 0.2g tetraethylborate (4.3), accurate to 0.001g, quantitative transfer to the quantitative container, plus
Water volume to 10mL.
Note. sodium tetraethyl borate in a dry environment to quickly weighed, the solution is now with the current use.
4.10 acetic acid - sodium acetate solution (pH = 4.75). Weigh 1.36g sodium acetate (4.4), accurate to 0.001g, quantitative transfer to the quantitative container,
Add 90mL of deionized water, with glacial acetic acid (4.5) to adjust the pH to 4.75, with water volume to 100mL, is now with the current use.
4.11 standard stock solution (1000mg/L). organic tin standard stock solution concentration to organic tin cation concentration. Priority to use evidence
Standard substance (CRM) can also be prepared by weighing 0.112 g of tributyltin chloride (4.7) and 0.110 g of triphenyltin chloride
