I need help writing the Methodology for a Chromium Adsorption from waste water experiment. Please organise it in a chronological manner so I can easily follow the steps when performing the experiment.
Deliverables:
1. List the various options of absorbent that can be used and the preparation of Adsorbent Material
2. Preparation of the chromium solution.
[Only these two are needed for now, when I need the other methodologies, I’ll post as a new question]
THANK YOU FOR HELPING OUT!
