ABSTRACT: The valorization of agricultural waste in the treatment of our rivers can
be an alternative to waste management. This study deals with the use of mango kernel shells
in the depollution of the Bafing River (rural commune of Tolo, Mamou
prefecture) in the Republic of Guinea. Thus, the different concentrations of
ions found in April (low water period) were determined and which are: a
reduction of 35.64 mg/l (79.69%); a reduction of 41.53 mg/l (81.24%); and 47.53 mg/l (82.10%) and 3.83 mg/l (75.24%); 8.45
mg/l (81.72%); 11.67 mg/l (87.94%) at the sampling points P1, P2, and P3
respectively. In October (flood period), the concentrations found are 24.98
mg/l reductions (79.88%); 29.83 mg/l reduction (81.41%) and 35.15 mg/l (85.50%) at the
same sampling points P1, P2 and P3, respectively. This study can be considered as a water treatment alternative for
the village community of the Tolo sub-prefecture (Mamou prefecture).
