The contents of lead, zinc, cadmium, iron, cobalt, copper, nickel and chromium in Bove hair washer wastes, in wastes from rinsing of washer, and in wastes from felting process were determined by spectrophotometric methods because of their simplicity and relative availability.}, type={Komunikat}, title={Spectrophotometric Determination of Heavy Metal Traces in Wastes from Felt Production}, URL={http://journals.pan.pl/Content/123749/PDF/13_AE_VOL_29_3_2003_Matysek_Majewska_Spektrofotometryczne.pdf}, keywords={chemical wastes, heavy metals, spectrophotometry VIS}, }
