راهنمای تصویری برای اندازه گیری مقدار SO2 در نمونه های جامد توسط دستگاه کجلدال کمپانی BUCHI مدل K-360 مراحل کار را مرحله به مرحله دنبال کنید:
1. Place stopcock in horizontal position
2. Ensure distillation unit is preheated
3. Add reagents to SO2 absorption vessel
4. Fill first receiver with iodine solution and water
5. Fill second receiver with ethanol
6. Take away the distillate outlet tube
7. Attach the SO2 absorption vessel that will collect the distillate
8. Replace the standard suction tube with the long suction tube
9. Set the spacer into position for 500 and 750 ml tubes
10. Using a powerful mixer, products can be homogenized to provide a representative sample
11. Weigh the homogeneous sample into a beaker and hydrolyze with a mixture of NaOH and ethanol
12. Wait for 10 minutes
13. Rinse the sample into a sample tube
14. The sample is acidified with phosphoric acid prior to the distillation
15. Connect the sample tube to K-360
16. Start the distillation method
17. Discontinue the distillation when the volume in the first receiver reaches the neck of the flask
18. Empty both receivers into a 600 ml beaker and cautiously rinse all glass parts
19. Add distilled water to increase the volume to 400 ml
20. Add sulfuric acid to acidify
21. Titrate with sodium thiosulfate until the solution is colourless
22. Use the App KjelReports to obtain results and generate reports that can be saved as PDF, e-mailed or exported
