DESCRIPTION:Prof Gordon McKay will present an outline of his recent resear
 ch projects in Hong Kong and which have been primarily driven by his pione
 ering work on the development and application of cheap adsorbents in the e
 arly 70s at Queen’s University. He will describe the range of pollutants
 \, the sources and types of novel adsorbents\, the range of adsorber conta
 cting systems\, and he will outline some of his pilot plant scale R & D pr
 ojects.\n	\nIn the second part of his presentation Prof McKay will discuss
  some of the results obtained in the adsorption/exchange studies for the r
 emoval of dyes from textile effluents and the removal of metal ions from t
 he microelectronics industry effluents. There are typically four phases to
  an adsorption study: adsorbent selection\, equilibrium\,  batch and fixed
  bed studies. Equilibrium isotherms are used to define the capacity of an 
 adsorbent for a pollutant. Batch kinetics analyse adsorption rate process.
  These pollutant studies enable mass transfer coefficients\, diffusitiviti
 es and kinetic parameters to be determined. Most industrial systems are ba
 sed on fixed bed adsorption and there are several problems in trying the p
 redict the performance of fixed beds simply from equilibrium and batch stu
 dies. Therefore\, pilot scale fixed bed studies are undertaken prior to fu
 ll scale fixed bed design. Mass transfer and kinetic modeling on all the p
 hases of an adsorption study have been carried out.\n
