Synthesis, characterization and application of goethite …

FT-IR spectra of the synthesized goethite mineral (Fig. 2) show very broad IR band at 3174.1 cm −1, which can be attributed to the stretching vibration of surface H 2 O molecules.The characteristic sharp bands at 798.0 cm −1 and 892.4 cm −1 can be assigned to the Fe–O–OH bending vibration in α-FeOOH. The 656.7 cm −1 band is ascribed to …

The ties that bind

Catalano. Scientists believe that up to 50% of the trace metals in soils and urban environments may be bound to the surfaces of mineral grains — rendering the trace metals essentially unavailable for consumption or exposure. Researchers at Washington University in St. Louis wondered what holds them in place. "When minerals bind trace …
