There is immense potential for the industrial application of microbubble technology in bubble column to intensify multiphase flow mass transfer process. In this work, characteristics (bubble size distribution, gas holdup, specific interfacial area, and volumetric coefficient) were investigated systematically a microbubble-dominated column. A key process flue desulfurization, ammonium sulfite oxidation, was selected as gas–liquid contact reaction. Experiments performed laboratory scale (16 L)...
Based on the inhibition effect of methimazole (MMI) reaction luminol-H(2)O(2) catalyzed by gold nanoparticles, a novel chemiluminescence (CL) method was developed for determination MMI. Under optimum conditions, relative CL intensity linearly related to MMI concentration in range from 5.0 × 10(-8) 10(-5) mol L(-1). The detection limit 1.6 L(-1) (S/N=3), and RSD 6.0 10(-6) 4.83 (n=11). This has high sensitivity, wide linear range, inexpensive instrumentation been applied detect pharmaceutical...
