Experimental
Apparatus
Atomic absorption measurements for Cd and Cr were made using
a Shimadzu, AA660 V-3 (Kumamoto, Japan) flame atomic ab-
sorption spectrometer equipped with hollow cathode lamps of Cd
and Cr Photron (Victoria, Australia) at conditions indicated in
Table1.
Laboratory wastes, both untreated and treated by alumina and
chitosan, were analysed by ICP-MS using a Perkin–Elmer modelElan5000 Spectrometer (Connecticut, USA) in the TotalQuant
mode and an ICP-OES using a Perkin–Elmer model Optima 3200
RL (Connecticut, USA).
A Crison2000 pH meter (Barcelona, Spain), equipped with a
glass electrode and an AgCl/Ag reference electrode, was used for
measuring the pH of solutions.
