1. the method that the trichoro-aldehyde Waste Sulfuric Acid purifies, is characterized in that, adopting calcium-base bentonite, sodium bentonite or atlapulgite is that sorbent material carries out purifying treatment to the trichoro-aldehyde Waste Sulfuric Acid, and operation steps is:

  • Drop into 50~

    400 purpose calcium-base bentonites, sodium bentonite or the atlapulgite of Waste Sulfuric Acid weight 1.0~

    25wt% in Waste Sulfuric Acid, stir 0.5~

    3.0h under normal temperature, the organism such as the trichoro-aldehyde in Waste Sulfuric Acid, trichoroacetic acid(TCA) are adsorbed, absorption is carried out solid-liquid separation after finishing, and can obtain the satisfactory sulfuric acid of aldehyde contenting amount.
