Chloramine takes quite a bit longer to evaporate out of solution. That is why we need to treat our water with sodium thiosulphate. chlorine evaporates readily out of the water in about a day or so, but it takes over a week to let the chloramine to evaporate, if it does at all. It is because of the chlorine-ammonia bond that chloramine doesn't evaporate.
