摘要：

A method is described for determination of total P in lake sediments or biogenic material. The organic matter is destroyed by ignition. Material remaining after ignition is boiled in 1 N HCl and orthophosphate determined after dilution. The method generally gave lower results than the perchloric acid digestion method (97.7, 98.7, 94.4, 100.5 and 97.3%) for 4 sediment samples and 1 sample of dried leaves. The reproducibility of the ignition method was slightly less than that observed with the perchloric acid method. Recovery after addition of known amounts of hydroxylapatite to the sediment samples was 98.5-102.6%.
