Then the staff can shake for 5 minutes, wait for it to filter, then wash with a small amount of water, combine the filtrate and the washings, add 50mg of ammonium persulfate, dilute to 35ml with water, so it is necessary to conduct legal inspection, and compare it with the control solution made with 1.0ml of standard iron solution, it should not be deeper.
