- •
Adsorption of alkaline phosphatase by sediments of lakes and minerals were investigated.
- •
Activities of the alkaline phosphatase immobilized by minerals and sediments would be reduced.
- •
Enzymatic hydrolysis of organic phosphorus in the suspensions of sediments was investigated by 31P-NMR.
- •
Organic phosphorus would be enzymatically hydrolyzed when they released from sediments.
- •
Organic phosphorus could not be hydrolyzed directly at the interface of sediments-water by enzymes
