Under conditions with excess Na + (0.5 M NaCl), smectite Li coverages drop dramatically, while the surface Li loads of smectite and kaolinite are comparable under the same condition (Table 4). WebFirst found in Hector, California, hectorite may contain up to 1 – 1.2% lithium. Hectorite shows distinctive absorption features at 1400nm and 1900nm similar to other smectite clays including montmorillonite, and more distinctive features at 2300 and 2380nm. Other less distinct absorption features are sometimes found near 960nm and 1100nm. circumlocution language learning https://dickhoge.com
