Methods of Analysis by the U.S. Geological Survey National Water Quality Laboratory- Determination of Dissolved Aluminum and Boron in Water by Inductively Coupled Plasma-Atomic Emission Spectrometry

摘要: Inductively coupled plasma—atomic emission spectrometry is a sensitive, rapid, and accurate method for determining the dissolved concentration of aluminum boron in water samples. The detection limits are 5 micrograms per liter 4 boron. For aluminum, lower-level (about 30 liter) short-term precision (single-operator, seven days) about 5-percent relative standard deviation, long-term nine months) 8-percent deviation. boron, shortterm 4-percent longterm Spike recoveries ranged from 86 to 100 percent, 92 109 percent.
