In nature leonardite is rich in fulvic acid calcium.

The fulvic acid or humic acid is the body, in which some proper lipophilic group or hydrophilic group has been inducted, of the series of humate surfactants .

In humic, fulvic acid appears to be most active.

Biology fulvic acid(BFA)contains many kinds of amino acids,trace elements and beneficial elements,which could promote the growth and development of plant,improve the stress resistance and immunity,combine and absorb harmful elements in plant,improve the quality,and increase the yield.

A technique was studied for extracting calcium phytate,a product with high added value from wastewater in the production of starch with corns.

Rice bran was used as the raw materials to produce calcium phytate by ultrasonic method.

The operation methods of the sections of raw material selection, acid immersion, filtration and neutralization in the process of calcium phytate production was tried to be improved so as to better the product quality and increase the product yield, additionally the theoretical basis was provided.
