Abstract

The adsorption of a range of hydroxy organic compounds on alumina trihydrate was studied in sodium aluminate solutions: Langmuir-type adsorption isotherms were observed. The greatest percentage of surface coverage was seen for sodium gluconate followed by mannitol and sodium tartrate. Batch precipitation measurements were conducted using alumina trihydrate as seed and a strong correlation was found between inhibition of precipitation and percentage surface coverage. This work has implications for theories of how alumina trihydrate yield is affected by Bayer liquor organics.
