Based on any dipole interaction concept of adsorption, chloramine should be 
adsorbed better than chlorine and free ammonia and ammonium ion should be 
adsorbed as well. Now, I must say that I have not tested for ammonia, but the 
chlorine test reacts to chloramine as well and my results are zero test for 
chlorine/chloramine for 4-5 months under my conditions, if I use good quality carbon. 
The other question that I would like an answer to is does the alkaline 
environment of the carbon break the chloramine into chlorine and ammonia? I have 
some homework to do. I will try to measure the amount of water that goes through 
before chlorine is detected and I also need to measure pH and ammonia before 
and after treatment.
