Jar tests were used to study the removal efficiency and influence factors caused by common anions and organic compounds of bromide in water by a new magnetic ion exchange resin (MIEX). The results show that MIEX can remove bromide in pure water effectively. The removal rates of bromide by MIEX are all over 90% when the equilibrium time of ion exchange reaction between MIEX and bromide is 5 min and 3 min and the dosage is 10 mL/L and 20 mL/L

respectively. Even containing other common negatively charged matter which has inhibitory effect to some extent

the removal rates reach 50%. Anionic content and the selectivity of MIEX are the main influence factors to reduce bromide in water by MIEX. The existence of organic compounds decreases the removal rate of bromide in water by MIEX

which is approximately 70%. There are differences between anions and organic compounds in removal processes by MIEX. The equilibrium time of ion exchange reaction removing anions is about 5 min

while it takes over 20 min to remove organic compounds measured with UV 254 and DOC

respectively by MIEX with the dosage of 10 mL/L.
