SPECIATION OF COPPER, LEAD, MANGANESE AND ZINC AND CHARACTERISATION OF SEWAGE SLUDGE FROM WUPA TREATMENT PLANT, ABUJA, NIGERIA
ABSTRACT Speciation of Copper, Lead, Manganese and Zinc ions in three sewage sludge samples (fresh, digested and dry) from Wupa sewage treatment plant, Abuja were investigated using sequential extraction methods. Flame atomic absorption spectrophotometer was used for instrumental analysis. The sludge physicochemical parameters, total metal concentration using aqua regia digestion, speciation of metals under study, using single extraction with EDTA and sequential extraction analytical methods were determined. Analysis of variance ...
