Abstract：A synthesis method of pure zeolite 4A with dissolving aluminosilicate from activated coal kaolinite was introduced. The product was determined by XRD, TEM, whiteness instrument, etc. The results show that, the product with high crystallinity, the average particle size is 515 nm (sub-micro range). Whiteness degree between 95 and 98, reaches the first grade of GB1768～93. In the trace element dissolving-out experiment, the dissolvingout content is greatly reduced, below the safety margin of drinking water. And the liquid carrying capacity is 60～70 g /100 g zeolite.
