Batch kinetic experiments were carried out for the sorption of methylene blue onto activated carbon. The experimental kinetics were fitted to the pseudo first-order and pseudo second-order kinetics by linear and a non-linear method. The five different types of Ho pseudo second-order expression have been discussed. A comparison of linear least-squares method and a trial and error non-linear meth...
One of the most important environmental problems is water and soil contamination with heavy metal ions. In this direction, the aim of this investigation was biosorptive removal of Cr (VI) using calcium alginate and determination of isotherm and kinetic of biosorption. Materials and Methods: Using batch system, biosorption capacity of calcium alginate for removal of Cr(VI) ions was investigated...
The objective of this work is investigation of the adsorption and decomposition of Reactive Blue 19 from industrial wastewaters using laccase enzyme immobilized on activated carbon powder and fiber as adsorbent. Time, pH, temperature, stirring rate, the amount of the adsorbent, dye initial concentration, solution flow rate in the column and column height were studied as key operating parame...
The development of a practical screening procedure for phenylketonuria and the improvement in methods of chemical analysis have led to a realization that Folling's (1934) disease of phenylketonuria is not a single entity. In this commentary, the current view on some aspects of phenylketonuria will be reviewed and the problems illustrated by experience gained in the Phenylketonuria Clinic at the...
