摘要: AbstractThe determination of phosphorus content in LiFePO4 by the quinoline phosphomolybdate gravimetric method presence polyethylene glycol was investigated. The diameter precipitation particles (D10) increased from 2·34 to 18·52 µm when added, so cannot pass through G4 crucible filter plate. precision this for is 0·08–0·13% which three times higher than that traditional method, and recovery standard addition 99·76–100·24%.
