＜正＞In order to economically exploit seawater chemical resources,it is essential to adequately adopt the local natural resources such as the energy of the wind and sun,i.e.,solar pond *** simulating isothermal evaporation experiment as similar as the climate conditions in the Gulf of Thailand was designed to demonstrate the enrichment behaviours of sodium,potassium, magnesium,calcium and the rare elements including lithium,bromine,rubidium,and caesium in seawater in the Gulf of Thailand. Through this experimental study,a series of liquid- and solid phase samples through evaporating after filtrating were obtained and analyzed to reveal the enriched behaviours of sodium,potassium, magnesium,*** experiment results showed that potassium ion was gradually enriched in the liquid phase in the first stage,and then it was crystallized out in the forms of carnallite and only a few of potassium chloride formed at the late evaporating stage. Meanwhile,the concentrations of lithium ion and bromine ion are measured corresponding to flame atomic absorption spectrophotometer and spectrophotometer to reveal the enrichment behaviors of lithium and bromine in brine during isothermal evaporating *** results of experiment showed that lithium was enriched constantly at the first stage of evaporating,and then significantly up to 18.85 mg/L of lithium in solution;bromine in the liquid phase was enriched as similar as lithium with the highest concentration up to 6.0g/L in the mother *** thesis provides an important reference for the development process of bromine and lithium extraction from the seawater in the Gulf of Thailand. Those results provided a valuable reference for the comprehensive utilization of seawater in the Gulf of Thailand.

Sc and Y are key rare earth elements and are widely used in lamp phosphors,lasers and high-performance ***,highly efficient extraction and separation of Sc3.and Y3.is laborious,harmful,slow,and costly,strongly necessitating more efficient extraction and separation ***,we produced hydrated Sc3.-and hydrated Y3.-controlled graphene oxide（GO） membranes and find that both hydrated cations were completely self-rejected by the *** combining this selfrejection effect of the larger hydrated Y3.-controlled GO membrane and the rapid passage of the membrane through the smaller hydrated Sc3.,we proposed a strategy to separate Sc3.and Y3.by using a hydrated Y3.-controlled GO *** experimental results show that the permeation rate of Sc3.exceeds that of Y3.when the separation factor reaches 4.02,which can be attributed to the interlayer sieving effects of the GO *** finding illustrates the use of a forward osmosis process with a GO membrane for the efficient separation of Sc3.and Y3.by interlayer sieving,which provides a new effective and eco-friendly method for the separation of rare earth elements.
