CAMZ-S

Arsenic absorbent material for polluted soil

CAMZ-S

What is CAMZ-S

CAMZ-S is an arsenic absorbent assumed to be a main ingredient of an artificial zeolite.

It becomes possible to make strong arsenic adsorption power appear by giving the special process to the surface of an artificial zeolite.

Moreover, it has high arsenic adsorption capacity by making the best use of a wide surface area that is one of the feature of artificial zeolite.

Feature of CAMZ-S

High efficiency of arsenic adsorption
Because it is not a physical adsorption and the arsenic is chemically adsorbed, it is possible to adsorb strongly.
High adsorption capacity
Because the amount of the arsenic adsorption near the unit is large, processing by a little amount of the adsorbent addition is possible.
Simple use
It is not necessary to use together with other medicines basically, and it is possible to process it only with CAMZ-S.
Low negative environmental impact
An artificial zeolite (cycloid type resource/no include of injurious contents ) is a principal ingredient, so there is no danger of collateral contamination. And there is no load given to the processing ground.
Achieved processing with high stability
This strongly catches the adsorbed arsenic. The arsenic can be insolubilized with stability under the situation in which the load hangs.
Correspondence with the wide range of pH
An adsorption ability is demonstrated steadily in the wide ph range (ph/4-10). Basically, it is not necessary to adjust the ph of the soil as a preprocessing.
  • Shape : slurry

Elutingu examination

[eluting examination]

  1. Add CAMZ-S into the mock polluted soil at the rate of 4.6wt%, and it mix homogeneously. Afterwards, leave with the room temperature for 24 hours.
  2. Measure the concentration of arsenic elution based on the 46th elution test of which the Ministry of the Environment notified.
It is possible to decrease the elution level below the environmental standard.

Stability examination

[stability examination]

  1. Add CAMS-S into the mock polluted soil at the of 4.6wt% and it mix homogeneously.
    Afterwards,leave with the room temperature for 24 hours.
  2. The acid/alkaline solution made for a constant concentration and the soil are mixed at the rate of 10w/v%.
    ※Acid solution=H2SO4 , Alkaline solution=Ca(OH)2
  3. Elute is to be taken with the same operation of which the Ministry of the Environment notified.
  4. The filtration liquid made by 3 is collected, and the concentration of arsenic of the solution is measured.
A steady performance is demonstrated under a severe condition.
