Abstract:
There was successful retrieval of metallic aluminum from discarded compact discs in the presence of an active alkaline stripping solution (sodium hydroxide, sodium phosphate, and sodium carbonate) with sodium lauryl sulphate as a viscosity modifier at 80oC and 20KHz ultrasonic frequency. At standard conditions and precautions, the qualitative and quantitative isolation of metallic aluminum with sodium hydroxide/ammonia solutions and 0.5M sulphuric acid yields 0.012Molar, 0.0953g/mol, and 21.99% aluminum salt from 10g of compact disc materials.
