Investigation of dye adsorption onto activated carbon from the shells of Macoré fruit.

The activated carbon obtained from the shells of Macoré fruit was used as an adsorbent for the removal of dyes such as methylene blue (MB) and methyl orange (MO) from synthetic contaminated aqueous solutions. It holds that the adsorption is more favourable at acidic pH, with an optimum adsorption at pH = 2. At this pH, the adsorption rate is more than 98% for the two dyes.

Using fluorescence spectroscopy EEM to evaluate the efficiency of organic matter removal during coagulation-flocculation of a tropical surface water (Agbo reservoir).

This study evaluate the use of fluorophores A, C and T fluorescence intensities to access the coagulation efficiency for removing dissolved organic carbon (DOC) in the raw water from Agbo reservoir in Ivory Coast. A coagulation-flocculation was conducted with aluminium sulphate as coagulant and DOC residual and fluorescence intensities were acquired. The consistency of fluorescence data was evaluated to ensure that no inner-effect, quenching or enhanced intensities affect the data.
