In consideration of the adsorption of solvent,diluent and solute molecules on the surface of a stationary phase,a new equation for solute retention in liquid chromatography is presented. This equation includes three parameters: the displacement equilibrium constant( K _ sd ) between the solvent and diluent molecules on the surface of the stationary phase,the total number( N ) of the solvent and diluent molecules released from the stationary phase after one solute molecule being adsorbed,and the parameter( I ) related to the thermodynamic equilibrium constant for the solute adsorption on the stationary phase. Over the whole concentration range of the solvent in the mobile phase,the experimental retention data can be well described by this equation,parameters K _ sd ,N and I can be obtained by the regression analysis of the experimental retention data,and consequently the number of the solvent and the diluent molecules displaced by one solute molecule from the stationary phase can also be derived at different solvent concentrations in the mobile phase.

Flower-like SnO2 nanopowders prepared by a hydrothermal method were surface modified with palla- dium via impregnation. The crystal structure, morphology, and surface chemistry states of the samples were characterized by means of X-ray diffraction （XRD）, scanning electron microscopy （SEM）, and X-ray photoelectron spectroscopy （XPS）, respectively. The gas sensing performances were also investigated. For a hydrothermal temperature of 220 ℃, flower-like SnO2 nanoparticles consist of nanorods with diameters of 40 nm and lengths of 100 nm. The XPS and XRD results reveal that palladium exists in the Pd0 chemical state but the crystal is too small to be detected. The 0.3 wt% Pd modified SnO2 sensor shows better sensi- tivity, up to 21, for 70 μL/L ethanol gas at an optimal working temperature of 250 ℃. The quick response time （3 s） and fast recovery time （-20 s） are the main characteristics of this sensor.

The global ocean sequesters a great amount of dissolved organic carbon(DOC),which is mainly originated from indigenous microbial activities(such as photosynthesis and chemoautotrophy)in the water column,as well as various exogenous sources such as riverine input,sediment mobilization,aerosol dissolution,hydrothermal vent effusion,and others(Cai and jiao,2023).
