Neutron and X-ray diffraction measurements on highly concentrated aqueous LiCl solutions

摘要: Abstract New neutron and X-ray diffraction experiments have been performed on concentrated aqueous lithium chloride (LiCl) solutions under ambient conditions, as a function of the salt concentration. The concentration range covers wide region, between ion-pair:water ratios about 1:3 (which is solubility limit) 1:15 still rather high value). Data interpreted by means Reverse Monte Carlo structural modelling method. It has established that meaningful ion–water water–water partial radial distribution functions may be derived even from such limited amount data, provided measurements method interpreting them are chosen sensibly. new data their analyses suggest presence Li+ cations with only 3 (or less) coordinated water molecules around them. At highest concentration, one counter-ion found to penetrate into first hydration sphere ions.
