Samples (10 ml) taken from the adsorption reactor were filtered through 0.45 m filter paper and the filter paper with biomass was digested at 600° C for 2 h. Five millilitres of HNO3 was added to the digested biomass, and the resultant solution was diluted to 25 ml with distilled water. The nickel concentration in this solution having a pH of 2.0 was measured. This mea-
surement was used in calculating the nickel content of digested biomass.
这篇文献中提到这种直接利用高温的方法,然后向其中加入浓硝酸,溶液中的镍离子即为污泥中的镍离子浓度
