So study on the Patten of phosphorus combination in water and deposits, and how the pattern changes from one to another is the key to deal the eutrophication problem in Guanting Reservoir. In this paper ,one array of samples of Ca_2-P、Ca_8-P、Al-P and Fe-P was taken, according to the inorganic phosphorus classification method in lime-soil. By burning the samples, the quantity of Org-P is measured and the quantity...
