Rodi set up. Anion resin question

Colin_S · Jan 10, 2020

Hello all
just trying to get some info on Anion resin. I'm in UK and where I get my resin from https://www.osmotics.co.uk has cation resin, but not anion resin.
I used silicate specific resin https://www.osmotics.co.uk/products/1-Litre-Colour-Changing-Silicate-Specific-Resin.html as a substitute.
trying to do a bit more research, anion is negatively charged targeting nitrates, phosphate, bromide, fluorine and chloride, I'm finding it hard to find something that states its anion resin in the uk
can anyone help me out as to what would be the equivalent to brs's anion resin
maybe @Ryanbrs or @randyBRS can help me
thanks

Can you get mixed bed cation/anion?

A resin that binds silicate will bind all anions.

thanks, could you explain why?

Randy Holmes-Farley · Jan 10, 2020

a silicate resin is a marketing term for an anion resin that they think, or want you to think, binds silicate (an anion) especially well.

I discuss ro/di including how these resins work here:

Unless you are going to recharge them yourself, using a mixed bed with both can be simpler.

my current set up, is both cation, Anion and then mix. what do you mean recharge them yourself?

Anion and cation resins can be recharged chemically. Mixed beds cannot. I describe it in the article, but haven’t bothers doing it myself. Too much effort.
