Made colloidal gold by accident.

After using nitric acid boils to remove copper and other metals I started rinsing in distilled water alternating rinsing in hydrochloric acid. During these rinses the water started turning purple. Now I have a jug of purple water. The purple sticks to the sides and bottom of any vessel you put it in. I think it’s colloidal gold any ideas on how to fix this

An old post, but perhaps worth reading.

If you alternate between Nitric and HCl you NEED to roast between each round as you will not get rid of all Nitrates/Chlorides and you create a little AR each time.
This might be the cause of your colloids.
