Location: Group 15, Period 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, H2SO4, and HF aqueous matrices water and NH4OH. Stable with all metals and inorganic anions at low to moderate ppm levels under acidic conditions; precipitates with several metals occur in neutral media at higher concentrations. Stability: 2-100 ppb levels - stability unknown - in 1% HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 0-1% HNO3 / LDPE container. P Containing Samples (Preparation & Solution): Metal (never found free in nature); Oxides (water soluble); Ores (naturally occurring only as the phosphate, except for a few rare minerals found in meteorites - Na2CO3 fusion in Pt0); Organic Matrices (dry ash mixed with Na2CO3 in Pt0 at 450°C then increase heat to 1000°C to fuse; or, perform a H2SO4 / H2O2 acid digestion). |
