These drugs have mole fraction solubilies between 1.0 × 10-5 and 1.2 × 10-2, which are high enough to make the supercritical impregnation process a feasible alternative to impregnation employing organic solvents. Crossover pressures of (150, 180, and 150) bar were found for benzocaine, metronidazole ...

Gold is a rare and noble metal with atomic number of 79. Several techniques including both spectrometric and electrochemical methods are widely used to determine gold level in real samples. As a result of low concentration of gold in environmental samples, sample preparations such as extraction, clean-up, and pre-concentration before instrumental analysis are mandatory. Thus, a pre-treatment method (dispersive liquid–liquid microextraction (DLLME)) for gold pre-concentration and inductively coupled ...
