Major Factors

The ebulliometric technique for determination of infinite-dilution activity coefficients is examined. A simple mathematical model of ebulliometer is formulated to derive and analyze corrections accounting for the difference between the composition of the ebulliometer charge and that of the equilibrium liquid. Our own experimental equipment employing the comparative ebulliometric setup is described along with the measuring procedure and calibration. Error analysis is carried out identifying major factors limiting the accuracy of the determination.

We propose and test an efficient approach for the assessment of the enthalpies of vaporization of ionic liquids at the reference temperature 298.15 K. The approach is based on activity coefficients at infinite dilution of volatile organic solutes in ionic liquids bearing the imidazolium cation of the general formula [Cnmim][Anion].

Management Work

At this stage, China s environmental protection work is in full swing, andthe path of sustainable development has become the direction of China s futuredevelopment. This requires economic development and environmental health as well as the health of the atmospheric environment. It is necessary to pay full attention to the detection of atmospheric environmental quality and provide a basis for the treatment of air pollution problems. This paper mainly analyzes the application of the determination method of volatile organic pollutants in the atmosphere, and mainly studies the application of GC/MS measurement methods. It is hoped that this theoretical study will help volatile organic pollutants in the atmosphere. The actual management work is carried out.
