Provided is a method for measuring water insoluble substances in sodium humate, which belongs to the field of chemical experiment detection, the method comprising the following steps: S1, extracting the water insoluble substances; S2, carrying out suction filtration; S3, carrying out weighing; and S4, calculating a result. The beneficial effects are: with the nylon filter cloth, the sodium humate is not adsorbed on the nylon filter cloth, and only the water insoluble substances are left on the filter cloth, the filtration is changed into the suction filtration, the water consumption is reduced, the detection time is shortened, the efficiency is improved, and the detection result is accurate and stable. |
