這是因為Chlorine溶入水內 , 其化學作用會與bacteria , virus&germs的蛋白質react . Cl2 + R-NH(protein)-------->R-NCl + HCl 而此氮-氯复合物 , 從而干擾了細胞的代謝 , 最後細胞死亡 . 另外有話Cl使細胞膜通透性改變 , 亦影細胞生存 . 總之disinfectant接觸到cell會change cell normal function then normal metobolism , finally the cell will die .
Chlorine gas is halogen and it is toxic. it damages germs life.Germs will die because of poison. So, you can only add a little into water to
kill germs,but you cannot add too much, or the water will be poisonous and corrosive . If you drink it you will get hurt.
