In view of the valorisation green microalga Scenedesmus obliquus biomass, it was used for biosorption two nonsteroidal anti-inflammatory drugs, namely salicylic acid and ibuprofen, from water. Microalgae biomass characterized, by determination point zero charge (pHPZC), Fourier transform infrared (FT-IR) analysis, simultaneous thermal analysis (STA) scanning electron microscopy with energy dispersive spectroscopy (SEM/EDS). Kinetic equilibrium batch experiments were carried out results found...
In the present work, adsorptive removal of diclofenac from water by biosorption onto non-living microalgae biomass was assessed. Kinetic and equilibrium experiments were carried out using two different strains, namely Synechocystis sp. Scenedesmus Also, for comparison purposes, a commercial activated carbon used under identical experimental conditions. The kinetics adsorption fitted pseudo-second order equation, corresponding kinetic constants indicating that faster than carbon. Regarding...
In this work, zebrafish embryo bioassays were performed to assess the efficiency of microalgae in removal acetaminophen from water. Chlorella sorokiniana (CS), vulgaris (CV) and Scenedesmus obliquus (SO) strains used for water treatment. Toxic effects on caused by effluents treatment compared with those observed under exposure experimental solutions known concentrations acetaminophen. The three allowed reduction concentration its toxic effects, but CS was most efficient one. At end batch...
Microalgae are aquatic photosynthetic prokaryotic or eukaryotic microorganisms which cultivation for the fixation of CO2 and production biofuels has received large attention. However, sustainable development an algal biorefinery is still a challenge. In this context, valorization microalgae biomass wastewater adsorptive treatment may be option to explore. Recently, presence emerging contaminants (ECs) in natural waters associated risks have led great concern, especially case pharmaceuticals....
In this work, thermogravimetric analysis (TGA), differential thermogravimetry (DTG), and scanning calorimetric (DSC) were used to assess the combustion of microalgae biomass, a bituminous coal, their blend. Furthermore, different correlations tested for estimating high heating value biomass with both materials possessing similar values. TGA evidenced differences between studied fuels, but no relevant interaction occurred during co-combustion, as shown by DTG DSC curves. These curves also...
The performance of a polymeric resin (Sepabeads SP207, from Resindion, Binasco, Italy) was compared with that an activated carbon (GPP20, Chemviron Carbon, Feluy, Belgium) in the adsorption acetaminophen and ibuprofen either ultrapure or waste water. Kinetic equilibrium experiments were carried out under batch operation conditions, fittings obtained results to different models determined. kinetic experimental fitted pseudo-first -second order equations, corresponding rates evidenced...

Microalgae-based water treatments for the removal of different types pollution have been gaining considerable attention during last few decades. However, information about microalgae potential in pharmaceuticals and personal care products (PPCPs) ecotoxicological outcomes is still limited. Therefore, this work, we aimed at investigating salicylic acid from by three strains, namely Chlorella sorokiniana, vulgaris Scenedesmus obliquus. For such a purpose, photobioreactors were operated under...
This work aimed to compare the adsorptive removal of diclofenac from ultrapure and wastewater by different adsorbents. Batch kinetic equilibrium experiments were carried out using two activated carbons (GPP20 WP70, Chemviron Carbon) a non-ionic polymeric resin (SP207, Resindion). The pseudo-second-order equation fitted experimental results corresponding k2 (g mg−1 min−1) determined for was one order magnitude higher than resin. Langmuir–Freundlich isotherm. maximum adsorption capacity (Qm,...
Benzotriazole is used as corrosion inhibitor in many industrial sectors, such the dairy industry. Due to its widespread use various applications and everyday consumer products, this chemical easily reaches aquatic environment, where it may have deleterious effects. In fact, benzotriazole has been included among so-called emerging contaminants. work, occurrence fate of a based anticorrosive (BTA-A) during wastewater treatment industry assessed. At dairy, new system for on injection pure...
