The dithiocarbamate-modified porous starch (DTCPS) was synthesized. It is a cheap sorbent with super adsorption ability for V(V) ions removal from aqueous solutions. Surface structure of DTCPS was confirmed by using SEM, Fourier transform infrared spectra and TGA. The DTCPS has many micropores, which favours the adsorption of V(V) ions. Adsorption results indicate that mechanism is predominately based on electrostatic attraction. The adsorption of V(V) ions on DTCPS was largely dependent on the pH value, and the optimal pH was 3.0. In such solution, the decavanadate V10O26 and V10O27(OH)5− are main species. They adsorbed to DTCPS following the pseudo-second-order equation and Langmuir isotherm.

A series of heterometallic magnesium diruthenium(ii,iii) carbonates were synthesized from reactions of Ru2(CO3)43− and Mg2+ in aqueous solution. A variety of factors closely related to the structural and magnetic properties have been fully discussed.
Characteristics of an aminated glucose and its complex with Cu (II) were investigated by FTIR, 1H-NMR and UV spectroscopy, respectively. Compared with glucose, the FTIR spectrum of an aminated glucose showed a moderate peak at 1 629-1 608 cm(-1) which was attributed to deltaNH vibration, suggesting that glucose reacted with ethylenediamine. The 1H-NMR spectrum of an aminated glucose demonstrated the signal of the C1 hydroxy proton and one of the amino proton at 4. 82-4. 79 ppm, illustrating that the amino of ethylenediamine was substituted for the hydroxy group of C1. As for UV spectra, an aminated glucose did not show absorbance in the ultraviolet region while its complex with Cu(II) had obvious absorption peak at about 236 nm. The complex ratio of the aminated glucose to Cu(II) was about 1 to 1 and the stability constant of its Cu(II) complex was 6.8 x 10(7) L x mol(-1).
