Abstract

Nd(HGlu)3.3H2O complexes were successfully synthesized using neodymium (III) nitrate and glutamic acid solution. Effects of glutamic acid concentration, preparation times and glutamic acid/Nd ratios on the reaction performance and the structure of the complexes were investigated. These fabricated complexes have been characterized by infrared spectroscopy (IR), thermogravimetric analysis (TGA) and mass spectrometry (MS). The obtained results showed that Nd[HGlu]3.3H2O complex improved the growth of Paris polyphylla Smith as compared to the control sample.

Keywords: Glutamic acid, Nd(HGlu)3.3H2O, complex, growth , Paris polyphylla Smith.
