3 Fundamentals
The antifouling paint dry sample with a suitable acid solution was sealed microwave digestion, the rush acid, the volume was treated as ascorbic acid group
Modifiers, effective use of the existing graphite furnace atomic absorption spectrometry (GFAAS) or to meet the precision [inductively coupled plasma
Emission Spectrometry/Mass Spectrometry (ICP/MS), X fluorescence spectrometry (XRF) and inductively coupled plasma atomic emission spectrometry (ICP-AES), etc.] measured
The concentration of a given sample of tin. Then, based on a simple formula can calculate the tin content in the sample.
4 Reagents

hydrochloride (rho~1.19g/mL).
Nitrate 4.2 (rho~1.42g/mL).
4.3
sulfate (rho~1.98g/mL).
4.4
for the two test water or distilled water GB/T 6682-2008 requirements.
4.5 volume fraction of 10% hydrochloric acid solution
with hydrochloric acid (4.1) and a volume ratio of distilled water was prepared 1.9 ratio of volume fraction of 10%
Hydrochloric acid solution.
Completely dissolved, the solution was transferred to 100mL volumetric flask, constant volume, and mix.
4.7
tin standard solution, its configuration is as follows.
a) 1mg/mL tin standard stock solution. You can use a commercially available standard solution to meet the requirements or prepared as follows. Weigh 1.0000g
Tin (purity not less than 99.9%), placed in 200mL beaker, add 10mL water, 15mL of hydrochloric acid (4.1), taking close
Sealing measures to prevent solution evaporation, constant temperature (50 ± 2) °C heated to a metal tin is completely dissolved, cooling, the solution is transferred to 1000mL capacity
Flask with a volume fraction of 10% hydrochloric acid solution to volume, and mix.
