Specific features of the determination of arsenic in soils by electrothermal atomic absorption spectrometry with the injection of suspensions

Atomic spectrometry update – a review of advances in environmental analysis

“…New procedures involving slurry sampling ETAAS included a matrix-modier-free method 237 for the measurement of As in soils; a procedure 238 for determination of Bi in sediments using platform atomisation, NbC permanent modier and Ba(NO 3 ) 2 chemical modier; and a method 239 for the determination of As, Cd, Cr, Cu, Ni and Pb in moss. The latter involved sonication of pulverised moss (1-50 mg) with 0.2 M HNO 3 and 0.01% Triton X-100 for 25 seconds prior to injection into the furnace.…”

“…An ICP-TOF-MS method 260 for determination of Pt in algae and water allowed the impact of hospital waste to be estimated. Simultaneous measurement 261 of 237 Np, 239 Pu and 249 Pu was achieved by using 242 Pu as a yield tracer for both elements. Results obtained for NIST SRM 4357 (ocean sediment powder) were consistent with those reported in the literature.…”
