Anomalous Temperature Dependence of NQR Frequencies
The anomalous temperature dependence of NQR frequencies which is often observed in crystals in which there is reorientational motion of ions or molecules is considered. Two theories of the phenomena, the jump rotation theory and the pseudo-spin theory, are described, and their successes and failures are discussed. The importance of considering other properties such as pressure dependence of NQR...
متن کاملAdsorption of 4-Chloro-2-nitrophenol onto Nano-ZnO
Nano-ZnO was employed for the adsorption of 4C2NP from aqueous solutions in batch equilibriumexperiments to investigate its adsorption properties. The quantity of 4C2NP adsorbed onto nano- ZnOsurface was measured by UV-Vis spectrophotometer. The effects of contact time, adsorbent dose, pH, andinitial concentration of 4C2NP were investigated. The adsorption found to be strongly influenced by all...
متن کاملKinetic and thermodynamic studies of adsorption of 4-chloro-2-nitrophenol on nano- Ti02
Adsorption capacity of 4-chloro-2-nitrophenol (4C2NP) onto nano-Ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-TiO2 dosage, initial pH and initial 4C2NP concentration. Optimum conditions for 4C2NP adsorptionwere found to be initial pH z 2, nano-TiO2 closer- 0.01 g and equilibrium time 1 h. The adsorptionkine...
