Effective removal of cationic dyes from aqueous solutions by using black cumin (Nigella sativa) seed pulp and biochar
نویسندگان
چکیده
Black cumin seed pulp (C), as well biochar (CC) produced via pyrolysis of black were used to remove methylene violet 2B (MV) and basic yellow 28 (BY28) from aqueous solution. Adsorption isotherms kinetics applied at 10, 25, 35 °C. The adsorption on the surface was exothermic; heat values lower than 0. capacities BY28-C, BY28-CC, MV-C, MV-CC 212.8, 625, 164, 909 mg g-1 25 °C, respectively. data examined with Freundlich, Langmuir, Temkin, Dubinin-Radushkevich (D-R), Flory-Huggins (F-H) isotherm models. fitted pseudo first-order second order equations. equation gave a better fit equation.

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...

The incidence of food hypersensitivity and food allergies is on the rise and new treatment approaches are needed. We investigated whether N. sativa, one of its components, thymoquinone, or synthetic opioid receptor (OR)-agonists can alleviate food allergy. Hence, ovalbumin (OVA)-sensitized BALB/c-mice were pre-treated either with a hexanic N. sativa seed extract, thymoquinone, kappa-(U50'4889) ...
