The features of carrier induction crystallization are that a large amount of the grains of suitable carrier are added in precipitation reaction system, the grains speed reaction up, precipitates sedimentate with the grains and the time of precipitation process is shorten.

Using the micropore structure of cotton fiber,penetrate Ba~(2+)into the cotton fiber internal,contact PO_3~(3-) and generate phosphoric acid barium and phosphoric acid hydrogen barium crystallization sedimentation in the micropore of cotton fiber.

Based on the micropore structure of cotton fiber, to penetrate Ba2+ into the cotton fiber and contact PO33- to generate phosphoric acid barium and phosphoric acid hydrogen barium crystallization sedimentation in the micropore of cotton fiber.

Focusing on the research progress of the precipitation and crystallization of proteins,the special phenomenon and crystallization mechanism of such biological macromolecules as proteins,enzymes,etc.

Development of fluidized induced crystallization precipitation technology in inorganic wastewater treatment;

A technology of heavy metals removal from wastewater with fluidized bed by inducing crystallization was studied.

The technology with fluidied bed by inducing crystallization has many advantages , such as high removal efficiency, low cost, small space and wide range eligibility of heavy metal kinds.
