TL;DR: In this paper, pristine multi-walled carbon nanotubes (MWCNTs) can effectively activate peroxymonosulfate (PMS) and peroxydisulfate to produce sulfate radicals for oxidation of phenol solutions.
Abstract: Employing metal-free nanocarbons or carbonaceous materials as a catalyst for environmental water remediation is a promising clean approach because the green carbon materials can completely prevent the potential toxic metal leaching and secondary contamination to water body. This study reports that pristine multi-walled carbon nanotubes (MWCNTs) can effectively activate peroxymonosulfate (PMS) and peroxydisulfate (or persulfate, perdisulfate, PDS) to produce sulfate radicals for oxidation of phenol solutions. Surface nitrogen modification was conducted by a facile synthesis via annealing MWCNTs with ammonium nitrate at a low temperature and the nitrogen modified MWCNTs (N-CNT) was characterized by a variety of techniques. It was found that surface nitrogen modification of MWCNTs produced different effects on PMS and PDS activation. N-CNT can significantly improve the phenol degradation with PMS, but decrease the degradation efficiency with PDS. Reaction kinetics and the mechanism in catalytic oxidation of phenol solutions with sulfate radicals over CNT-based materials were discussed.

TL;DR: In this paper, the authors present a state of the art on the review of adsorption isotherm models in an exhaustive manner on the basis of two, three, four and five parameters respectively.
Abstract: Industries generating wastewater with elevated concentrations of pollutants (e.g. metals, dyes, phenolic compounds, anions, etc.) need specialized atreatment systems. Adsorption is one of the most extensively applied techniques for the removal of pollutants from the industrial effluents. The prominent and emerging trend of subjecting biosorbent in the adsorption technology is mainly because of their natural existence, abundance, renewable, biodegradable and economic features. The adsorption isotherm equations used to describe the experimental data and the thermodynamic assumptions of the models often provide some insight into the sorption mechanism, the surface properties and affinity of the biosorbent. This paper presents a state of the art on the review of adsorption isotherm models in an exhaustive manner on the basis of two, three, four and five parameters respectively. Focuses on the various sources of agricultural byproducts as biosorbents and describes on the potential applications of different adsorption isotherm models for the evaluation of the wastewater pollutants biosorption. It is evident from the literature survey that various adsorption isotherm models have been considered under study by the researchers but mostly two and three parameter isotherm model were best fitted the equilibrium data. This paper reviews the adsorption isotherm models on the basis of parameters that can be applied for exploring a novel biosorbents.
