How To Use Hydrofluoric acid In A Sentence
-
Magnesium oxide paste has been suggested as an alternative to calcium gluconate gel. 15 Bracken et al. compared the use of 0.13 percent benzalkonium chloride solution, 2.5 percent calcium gluconate gel and 30 percent magnesium sulfate/6 percent magnesium oxide paste to a control (water) for treating dermal burns induced by 70 percent hydrofluoric acid. 26 In this study, calcium gluconate gel was the only agent effective in limiting the extent of the burn.
