Abstract
In this part of studies, an improved stationary plutinum electrode polarograph named Oxigraph was proved to be applicable to measure dissolved oxygen of solutions under high hydrostatic pressure. Experimental results are as follows; 1) Under high hydrostatic pressure, limiting current value concerning oxygen wave of solution increases its degree in proportion to the strength of applied pressure. The oscillation of limiting current value widens under high pressure generally. 2) Under high pressure up to 1,500 Kg/㎠ ., the electrical potential inducing oxygen reduction wave is not influenced in buffer solution. 3) When the same charging potential as at normal pressue is charged, the stability and reproducibility of limiting current value does not alter at high pressure up to 1,500 Kg/㎠ . 4) At the moment of the appilication of high hydrostatic pressure, a transient increment of limithing current value is observed in proportion to both dissolved oxygen amount and pressure intensity. 5) Under high pressure, the influence of temperature on the limiting current value resembles to that under normal pressure. 6) In glutinous solution such as 1-5% dextrin-Ringer's solution, the limiting current value decreases in proportion to the concentration of glutinous substance both under normal and high hydrostatic pressure. The increment of limiting current value of glutious solution under high pressure is inferior to that of Ringer's solution only. On the other hand, the increase of final ascendent under high hydrostatic pressure is dominant in glutinous solution. Hence, it seems that high pressure minimizes the influence of mixed ghitio us substance. 7) In buffer solution such as Ringer's solution, the influence of carbon dioxide dissolved a little is negligible for the measurement of limiting current under high pressure, too. 8) In neutral solution, the influence of added protein resembles that of dextrin under high pressure also.
