Abstract

PURPOSE: To remove efficiently and easily the heavy metal ions, by adding gelatin of an amount exceeding the solubility to the aqueous solution containing the heavy metal, regulating pH of the aqueous the solution to a specified value, after that, separating and ermoving gelatin which has not dissolved andthen removing the bubbles generated owing to the blown-in air.
