用色谱保留值法测定了单质碘和单斜硫在不同温度及压力下在超临界二氧化碳中的溶解度，并用超临界平衡饱和萃取法验证了测定值，结果满意．
The solubility of elemental iodine and monoclinic sulfur in supercritical carbon dioxide at different temperatures and pressures was determined by chromatographic retention method. The results were satisfactory with the supercritical equilibrium saturated extraction method.
