Recognizing chlorine
« on: December 24, 2009, 09:53:54 AM »
How can I detect chlorine in solution for example ?
It means which solution when I add chlorine to it changes colour or something else.

You can choose.

I need some types of compounds which react with this.
I prefer of course not organic ones.
But advanced organic chemicals will be pleasant too.

I need a test for presence of small amount of chlorine exactly.

Small amount of chlorine exactly. Do you mean quantitative analysis of ppm quantities?

Perhaps you should read into X-ray fluorescence (XRF).

Small amount.
Something like 1/15 of vial.

They have several detector methods used in pools and spas
orthotolidine
This page discusses it

Here is a page that has chlorine tests strips found via Google

Going to need to articulate what levels of detection you need.  But turning it into aqueous chloride and then doing an argentometric titration should do it.
