3 principle

3.1 Determination of organic tin content in the coating principle With ethyl acetate and other solvents as the extraction solvent, ultrasonic extraction of organotin in the sample. In the extract, add acetic acid - sodium acetate buffer Solution, sodium tetraethyl borate as a derivatization reagent, the organic tin in the extract was derivatized with n-hexane extraction of the organic extract Tin derivatives were detected by gas chromatography-mass spectrometry (GC/MS). 3.2 Determination of soluble organic tin coating principle The sample is made into a coating film according to the product regulations, and the soluble organotin in the coating film is extracted with 0.07mol/L hydrochloric acid solution. In the extract, Acetic acid - sodium acetate buffer solution was added to the sodium tetraethylborate as a derivatization reagent, the organic tin in the extract was derivatized with n-hexane The organotin derivatives were extracted from the extract and detected by gas chromatography-mass spectrometry (GC/MS).

4 reagent

Caution --- Sodium tetraethyl borate is flammable. For the safe operation of sodium tetraethyl borate, please refer to the relevant chemical safety manual or supplier Safety warning instructions. Unless otherwise specified, only the reagents identified as analytical grade and above are used in the analysis and the requirements of GB/T 6682-2008 A level of water. 4.1 Sodium tetraethyl borate (NaBEt4) content ≥ 98% (mass fraction). ......
