Exfoliate systems without organic solvents - new type macro and extraction of metal ions microquantities
The article describes the results of studies on the solubility in the four systems diantipyrylmethane (DAM) - benzoic (salicylic acid) - HCl - H2O, geksildiantipirilmetan (GDAM) - benzoic (salicylic acid) - HCl - H2O at 298 and 323 K. Stable stratification appears when you add hydrochloric acid in the concentration range of 3.0-4.9 wt. % HCl. When replacing the ladies on GDAM observed broad area of delamination in the context GDAM - benzoic (salicylic acid) - 5 wt% HCl. The possibility of using stratified systems for the quantitative extraction of copper (I), cadmium, iron (III), thallium (III), tin (II and IV). There is no significant difference in the extraction of macro-and micro-metal ions in the system of benzoic and salicylic acids.
