Location: Group 13, Period 3
Atomic Weight: 26.98154
Coordination Number: 6
Chemical Form in Solution: Al(H2O)6+3
Storage & Handling: Keep tightly sealed when not in use. Store and use at 20 ± 4°C. Do not pipet from container. Do not return portions removed for pipetting to container.
Chemical Compatibility: Soluble in HCl, HNO3, HF and H2SO4. Avoid neutral media. Soluble in strongly basic NaOH forming the Al(OH)4(H2O)21- species. Stable with most metals and inorganic anions. The phosphate is insoluble in water and only slightly soluble in acid.
Stability: 2-100 ppb levels stable for months in 1% HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 2-5% HNO3 / LDPE container.
Al Containing Samples (Preparation & Solution): Metal (is best dissolved in HCl/ HNO3); α - Al2O3 (Na2CO3 fusion in Pt0); γ - Al2O3 (soluble in acids such as HCl); Ores (carbonate fusion in Pt0 followed by HCl dissolution); Organic Matrices (Sulphuric / peroxide digestion or nitric / Sulphuric / perchloric acid decomposition, or dry ash and dissolution in dilute HCl.Atomic Spectroscopic Information: (red text indicates severe at ~ concs.)
