摘要: Broadly speaking, indium (In) is extensively being used in the production of liquid crystal displays (LCDs). Nevertheless, LCDs, included various types end-of-life electronic devices (for example, discarded cellular phones), are generally without recovering indium. Thus, objective this work to recover from LCD phone. The authors putting forward a novel process order phones by means chloride-induced vaporization at relatively low temperature. samples first treated with an aqueous solution hydrochloric acid (HCl) alter structure indium(III) oxide found LCDs into compound and, therefore, enabling then vaporized. Finally, vaporized condensed on cooled surface apparatus and recovered. experimental results indicated that using 84.3 pct can be recovered phones.
