“…It can also affect the adsorption kinetics by changing the solubility of dyes or ionization state. Figure 5 a-b show the adsorption of dyes on the corncob surface at various pHs [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. It has been observed that corncob has the potential to adsorb MR and MO from an aqueous solution at different pH levels.…”

“…The dye adsorption is dependent on dye concentration, period of algal inoculation and quantity of algal biomass (Ezenweani and Kadiri, 2017). Chin et al (2020) reported that C. vulgaris decolourized methylene blue by surface adsorption through electrostatic interaction to 84% within 3 days. Furthermore, the ability of C. vulgaris to decolourize a variety of azo dyes through algal azoreductase enzyme was also reported by El-Sheekh et al (2009).…”

Re-dyeing of fabric materials using synthetic dyes (such as reactive dyes) is fast spreading in metropolitan Kano which causes serious damage to the ecosystems. This study was carried out to compare the potentials of Aspergillus terreus, Bacillus species and Chlorella vulgaris in bioremediation and adsorption of reactive red 198 (RR198) dye used in fabric re-dyeing. This was achieved through inoculation of pure cultures of the organisms in the dye solution. The highest percentage adsorption for all the test organisms was recorded after 48 hours of inoculation, with Chlorella vulgaris displaying 86.4%, Bacillus species, 84.4% and Aspergillus terreus, 69.8% of dye adsorption. The results showed statistically significant difference in dye adsorption among the three species with Chlorella vulgaris having the highest adsorption potential compared to the Bacillus species and Aspergillus terreus. The adsorption process fitted with the Freundlich's isotherm, revealing a multilayer adsorption pattern. There is need for the introduction of better strategies that detoxify dyes before discharging into the environment to avoid further contamination. Keywords: Aspergillus terreus, Bacillus species, Chlorella vulgaris, Reactive red 198 (RR198) dye.

“…Microalgae are photosynthetic micro‐organisms that have shown in several studies their ability to remove organic matter, nutrients, heavy metals, and synthetic dyes from wastewaters (Chin et al, 2020; Fan et al, 2020; Fito & Alemu, 2019; Spain et al, 2021), but they have never been used for the treatment of HCQ contaminated water. In this context, this work aimed to evaluate for the first time the ability of living microalgae as an economical and environmentally friendly adsorbent to remove HCQ from an aqueous solution under different experimental conditions.…”

Wastewater contaminated with hydroxychloroquine (HCQ) poses a serious threat to the environment and human life. This study aimed to evaluate the ability of living microalgae to remove HCQ from an aqueous solution. Batch mode experiments were conducted under different conditions to investigate the effect of operating parameters on HCQ removal efficiency and mechanisms. Equilibrium, kinetic and thermodynamic study was also carried out to better describe the interactions between HCQ and microalgae. The maximum HCQ removal was 92.10 ± 1.25% obtained under optimal pH of 9.9 ± 0.1, a contact time of 45 min, a stirring speed of 300 rpm, an initial HCQ concentration of 20 mg/L, and a microalgae dose of 100 mg/L. The Langmuir isotherm and the pseudo-second-order kinetic model were best suited for the biosorption experiments, and the maximum biosorption capacity was 339.02 mg/g. The thermodynamic study showed that the biosorption process was exothermic and spontaneous. Experiments on real wastewater showed that the HCQ removal was not significantly affected by the presence of other contaminants in the water. Practitioner Points• The best HCQ removal was 92.10 ± 1.25% obtained under optimal conditions. • The Langmuir isotherm and the pseudo-second-order kinetic model were best suited for the biosorption experiments.• The maximum biosorption capacity was 339.02 mg/g.• The thermodynamic study showed that the biosorption process was exothermic and spontaneous.• The microalgae studied can be successfully used in HCQ removal from water.
