摘要：
Humic acid (HA) vias extracted by NaOH solution from black soil of Heilongjiang in China. Reaction characterization of rare earth elements (La3+, Ce3+, Gd3+ and Y3+) With KA. plas studied by Fourier transform infrared (FTIR) spectroscopy. Results showed that peaks (1600 cm(-1) and 1400 cm(-1)) in FTIR spectra of HA became strength after reaction, implying that carboxyl groups of HA reacted with rare earth elements.
