Subject:
adsorbents; adsorption; aqueous solutions; batch systems; boron; energy; enthalpy; entropy; environmental technology; freshwater; heat production; models; pH; temperature; zirconium
Abstract:
... A new adsorbent based on natural clinoptilolite and amorphous zirconium dioxide (ZrO₂) was prepared for the uptake of boron from fresh water. The sorption behaviour of this adsorbent for boron was investigated using a batch system and found to obey Langmuir, Freundlich and Dubinin–Radushkevich (D–R) isotherm models. The ZrO₂ loading level, pH, temperature, contact time, initial boron concentration ...

Chlorophyta; Cyanobacteria; biobased products; biomass; boron; carbon; chemical composition; environmental impact; environmental technology; hydraulic fracturing; microalgae; natural gas; nitrates; oils; wastewater; wastewater treatment
Abstract:
... Hydraulic fracturing technology is widely used for recovering natural gas and oil from tight oil and gas reserves. Large volumes of wastewater, flowback water, are produced during the fracturing process. This study examines algal treatment of flowback water. Thirteen microalgae strains consisting of cyanobacteria and green algae were examined. Wastewater quality before and after algae treatment, a ...

Subject:
aqueous solutions; boron; environmental technology; ice; inorganic ions; models
Abstract:
... This study explored the feasibility of progressive freeze concentration in boron removal and its concentration in aqueous solution. The influence of three key parameters in progressive freeze concentration on boron removal and concentration, namely, the advance speed of the ice front, the circumferential velocity of the stirrer, and the initial boron concentration, are investigated by conducting b ...

anodes; boron; chemical oxygen demand; comparative study; electrochemistry; energy; environmental technology; oxidation; pH; sludge; wastewater
Abstract:
... Electro-Fenton (EF) oxidation has high oxidation abilities and is widely used in the treatment of biorefractory and chemically refractory organic wastewater. However, it generates a large amount of iron sludge, which limits large-scale application. In this work, the comparative study of EF oxidation and anodic oxidation (AO) of the secondary effluent of petrochemical wastewater using boron doped d ...

Abstract:
... Triphenylborane–pyridine (TPBP) is an antifouling compound used in Asian countries, including Japan, and its residue has not been detected in aquatic environments to date. There are limited data on its fate for environmental management. The purpose of this study was to evaluate whether TPBP is degraded by metal ions in aquatic environments. TPBP with metal ions in 20 mM sodium acetate buffer at pH ...

Abstract:
... The aim of this work was to study the inhibition effect of boric acid and sodium borate on the treatment of boron containing synthetic wastewater by a down flow aerobic fixed bed biofilm reactor at various chemical oxygen demand (COD)/boron ratios (0.47–20.54). The inhibitory effect of boron on activated sludge was evaluated on the basis of COD removal during the experimental period. The biofilter ...
