Researchers used a method called ICP-MS to measure the amounts of bromine and iodine in a salt lake. They separated different cations in the lake using a special resin. The detection limits for bromine and iodine were found to be 0.015μg/g and 0.036μg/g, respectively. The precision of the measurements was between 2.21% and 3.64% for bromine, and between 4.21% and 4.88% for iodine. The recovery rates for bromine and iodine were between 93.6% and 100.5%. This method shows promise for future use in studying salt lakes.
