This document mainly introduces a chemical speciation method for aluminium in environmental water bodies, which is based on bromide extraction separation and ICP-AES for measurement.
This document details a procedure for determining aluminium speciation in natural waters, specifically addressing the ecological dangers of acid rain and the toxicity of aluminium to fish. The method utilizes Graphite Furnace Atomic Absorption Spectroscopy (GFAAS) to isolate toxic chemical forms of aluminium that do not correlate with total aluminium levels.
| Instrument | Agilent AA-475 and GTA-95 graphite furnace and autosampler |
|---|---|
| Purge gas | Argon |
| Mode | Peak height |
| Ash stage temperature | 1225 C |
| Atomize stage temperature | 2700 C |
The analysis is carried out using the Agilent AA-475 and GTA-95 graphite furnace and autosampler.
A sample volume of 5 uL is pipetted into a 15 mL disposable polypropylene centrifuge tube.
The atomization temperature is raised to 2700 C to increase sensitivity.
