Oxidation state of lanthanum phosphate
WebThe addition of the lanthanum to the bentonite allows the resulting complex to bind phosphates to form rhabdophane (LaPO4.nH 2 O). This product is commercialised in Australia under the name Phoslock®. ... As phosphate is charged (oxidation state of −3 in solution), phosphate molecules are more strongly attracted by iron. Comparing the ... WebHigh concentrations of lanthanum and lanthanum compounds are toxic in nature, so that the metal has to be handled carefully. Long-term exposure may cause lung embolisms and increases the chance of lung cancer when inhaled. If lanthanum accumulates in the human body, it can be a threat to the liver. Key Properties
