Abstract
In this study, the concentrations (mg / L) of trace metal elements (TME) in an effluent from an industrial soap and cosmetic unit (SCI11) were evaluated. Four (4) composite samples and a witness sample (1) were collected. Nine (9) physicochemical parameters (T, pH, EH, SS, Al, Cr, Fe, Pb, and Zn) were analyzed according to AFNOR standards.The results showed that these effluents are characterized by high mean concentrations of suspended solids (266.75 ± 147.20 mg / L and Cr (0.678 ± 0.068 mg / L) which are far beyond the reference values of the Service Inspection of Classified Installations (SIIC). On the other hand, the mean concentrations of TME Fe, Al, Zn, respectively at 0.585 ± 0.03 mg / L, 0.618 ± 0.030 mg / L, and 0.244 ± 0.015 mg / L are in agreement with the SIIC reference values. The study also found that the effluent is behaving like a reducer with a mean EH redox potential of (-13 ± 1.87 mV). Mean values of pH (6.67 ± 0.60) and temperature T (29.58 ± 0.82 ° C) are in the order of the values recommended by the SIIC. Overall, the PCA analysis has shown that this effluent is a source of TME pollution and physical SS pollution.Keywords
