Flow-injection spectrophotometric determination of yttrium with Arsenazo III
We proposed a simple flow-injection spectrophotometric procedure for the determination of yttrium using Arsenazo III and optimized various conditions (pH for color formation and sample, buffer systems, Arsenazo III concentration, injection volume, flow-rate, and mixing coils). The calibration was linear at least up to 1 mgY/L, with a detection limit (3σ) of 0.02 mgY/L, RSD of 0.8% (n = 11 at 0.40 mgY/L). A throughput of 60 injections h−1 can be achieved. The procedure was applied to ore leachates of reference materials and samples. © 1999 John Wiley & Sons, Inc. Lab Robotics and Automation 11: 279–283, 1999
