Equilibrium and kinetics of Safranin O dye adsorption on MgO decked multi-layered graphene

Highly efficient simultaneous ultrasonic assisted adsorption of brilliant green and eosin B onto ZnS nanoparticles loaded activated carbon: Artificial neural network modeling and central composite design optimization

“…In this study, equilibrium adsorption isotherm models such as, Langmuir, Freundlich, Tempkin, DubininRadushkevich, while their [13,31,32] liner form are shown in Table 5. All the model constants are evaluated from the slopes and intercepts of respective model equations are shown in Table 5.…”

Partition study of textile dye Remazol Yellow Gold RNL in aqueous two-phase systems

“…The removal of dyes from wastewater is a complex problem to resolve and different physicochemical processes such as [5]; adsorption [6], electrokinetic coagulation [7], ion exchange [8], electrochemical oxidation [9] and photocatalytic degradation [10] studies are routinely carried out to find solutions to this environmental problem [5]. However, these methodologies have their drawbacks, amongst which, the generation of hazardous waste or secondary intermediates, slow degradation rates and high costs are limitations that stand out.…”

MIL-68 (In) nano-rods for the removal of Congo red dye from aqueous solution

“…It is well known that many dyes and pigments are inert, toxic and difficult to biodegrade when discharged into waste streams. In addition to be being a health threat, the presence of dyes and pigments in water is highly visible and affects the water transparency, resulting in reduction of light penetration, and oxygen gas solubility in water [2][3][4]. Thus, removal of such toxic dyes from the wastewater is a crucial issue.…”
