Procedure
STEP 1 — Prepare Saline
- Prepare 60 parts saline using 1–5% salt mixed into distilled water.
STEP 2 — Split Saline Into Three Portions
- Divide the saline into three equal volumes.
STEP 3 — Adjust pH of First Portion
- Use citric acid to bring one saline portion to pH 4.
STEP 4 — Adjust pH of Second Portion
- Use sodium bicarbonate to bring one saline portion to pH 8.
STEP 5 — Add pH 4 Saline to Reactor
- Add the acidified saline to the reactor.
STEP 6 — Mix
- Mix for 10 minutes.
STEP 7 — Drain Saline
- Drain the pH 4 saline from the reactor.
STEP 8 — Repeat Wash With pH 8 Saline
- Repeat Steps 6–7 using the pH 8 saline.
STEP 9 — Repeat Wash With Neutral Saline
- Repeat Steps 6–7 using the remaining neutral saline.
