In this paper, the effect of sodium humate (HA-Na) and seawater on absorption SO2 in flue gas was investigated. At same time, effects initial pH value concentration desulfurization were also evaluated. The experimental results showed that had ability to absorb SO2. dissolved can react with HCO3– CO32– plasma produce CO2, which prompt reaction. Besides, addition HA-Na improve performance increas...

A novel method of improving the SO2 absorption performance sodium citrate (Ci-Na) using humate (HA–Na) as an additive was put forward. The influence different Ci-Na concentration, inlet concentration and gas flow rate on desulfurization were studied. synergistic mechanism by HA–Na also analyzed. consequence shows that efficiency is above 90% time added with rising from 0.01 to 0.1 mol/L. Both m...

The influence of oral sodium bicarbonate and aluminium hydroxide on the absorption of indomethacin has been studied in normal volunteers. While sodium bicarbonate appeared to increase indomethacin absorption, aluminium hydroxide markedly reduced both the rate and extent of absorption. The buccal absorption of indomethacin over the pH range 5-9 was also studied in normal volunteers, and showed t...

achieving a desirable percutaneous absorption of drug molecule is a major concern in formulating dermatological products. the use of penetration enhancers could provide a successful mean for this purpose. the aim of this study was to evaluate the effect of incorporating a few common penetration enhancers (in different concentrations) into a 0.5% w/w piroxicam (model drug) gel formulation, on th...
