Phase Solution

The solid phase-solution equilibrium has been studied in the MgCl2-tetrahydrofurane system. Below 28 °C the saturated solution of magnesium chloride is in equilibrium with the solid phase composed of MgCl2.4C4H8O, whereas at higher temperatures the equilibrium solvate has the composition of MgCl2.2C4H8O. The solvate MgCl2.4C4H8O forms tetragonal crystals composed of molecules of trans-dichloro-tetrakis(tetrahydrofurane)magnesium(II) complex. The solvate MgCl2.2C4H8O most probably represents a polymeric catena-di-μ-dichloro-trans-bis(tetrahydrofurane)magnesium(II) complex.

Magnesium Chloride Solution

Magnesium silicate, one of silicate materials, is widely used as adsorbent for sample cleanup in solid phase extraction as well as color reducing agent in the industry of sugar, paint, paper, ... In this research, magnesium silicate is synthesized by precipitation method. The synthesis process was optimized by experimental design with quadratic orthogonal experimental method. The optimal reaction conditions are as follows: the mole ratio of sodium silicate/magnesium chloride = 1:1, the speed of stirring sodium silicate solution: 177 rpm, the added flow rate of magnesium chloride solution: 3.86 mL/min, drying temperature: 98oC. In addition, it takes at least 6 hours to eliminate water adsorption at this temperature. The product has amorphous structure with average particle size of 116 m, surface area of 454 m2/g, and trioleate glyceryl absorption capacity of 110 mg/g. The efficiency in the removal of esters of glyceryl and fatty acids in hydrocarbons determination and the removal of matrix in the analysis of organochlorides are as good as that of commercial Florisil.

Antiviral Antibody

Immunoelectron microscopy (IEM) applied to rapid virus diagnosis offers a more sensitive detection method than direct electron microscopy (DEM), and can also be used to serotype viruses. One of several IEM techniques is that introduced by Derrick in 1972, in which antiviral antibody is attached to the support film of an EM specimen grid. Originally developed for plant viruses, it has recently been applied to several animal viruses, especially rotaviruses. We have investigated the use of this solid phase IEM technique (SPIEM) in detecting and identifying enteroviruses (in the form of crude cell culture isolates), and have compared it with a modified “SPIEM-SPA” method in which grids are coated with protein A from Staphylococcus aureus prior to exposure to antiserum.
