This article describes the influence of dissolved copper on the electrokinetic properties and transport of a copper oxychloride-based fungicide (COF) in porous media. The Zeta potential (ζ) of COF particles increases (viz. becomes less negative) with increasing concentration of Cu2+ in the bulk...

Because the extensive use of Cu-based fungicides, the accumulation of Cu in agricultural soil has been widely reported. However, little information is known about the bioavailability of Cu deriving from different fungicides in soil. This paper investigated both the distribution behaviors of Cu f...

Heterogeneous Fenton degradation of nitrobenzene (NB, 20 ppm) was investigated at room temperature and pH = 7 using 0.1 g L−1 of FeOCl (I), CuOCl (II), ZnOCl (III) and BiOCl (IV) metal oxychlorides catalysts in presence of ultrasonic (US, 20 kHz), ultraviolet (UV, 6 W, λ = 254 nm) and UV/US dou...

In this work, it is found that the hydrothermally-synthesized bismuth oxychloride can behave both the piezocatalysis and photocatalysis for the Rhodamine B dye decomposition. ∼99% decomposition efficiency is achieved after both vibrating and lighting the Rhodamine B dye solution for ∼96 min wi...

The new oxychloride, Ba27Pb8O8Cl54, has been synthesized by a high temperature solution method. It crystallizes as cubic brown block with unit-cell a = 22.547(2), space group Fm3¯m (No. 225). It features a complicated three-dimensional network composed of [Ba20O4Cl92] and [Ba14O8Cl36] units sha...

Excess copper in plants causes physiological alterations that lead to crop productivity losses. However, cupric fungicides have been utilized in the control of Alternaria solani and Phytophtora infestans fungi, which cause early blight and late blight in potato, respectively. Thus, this study ai...

The objective of this study was to measure the impact of the mechanized chlorpyrifos, copper oxychloride and myclobutanil application in a small peach orchard, on humans (operators, bystanders and residents) and on the productive soil. The mean Potential Dermal Exposure (PDE) of the workers (tra...

BackgroundThe target of this animal study was to clarify the influence of Copper oxychloride (COC) (at concentrations of 50, 100 and 200 mg/kg b.wt.) administration for ninety days on the brain tissues to evaluate its possible neurotoxicity.

The phase composition and local atomic and electronic structure of tin oxide layers have been studied by applying synchrotron X-ray absorption near edge structure spectroscopy. The linear combination analysis of the achieved results have been performed using first-principles calculated reference...

Based on the chemical and mineral composition of asbestos tailings, the asbestos tailings powder was pre-fired, formed into green body and finally heat-treated to prepare glass-ceramics through the processes of crystallization and sintering. The main crystal phases of the sample were forsterite ...

While many public health threats are now widely appreciated by the public, the risks from asbestos exposure remain poorly understood, even in high-risk groups. This article makes the case that asbestos exposure is an important, ongoing global health threat, and argues for greater policy efforts ...

Nickel matte (Ni3S2) is the most common feedstock for producing nickel oxide and nickel metal in associated refineries. Nickel matte is produced from sulfide or laterite ores, and contains around 73 wt% nickel. This study investigated the dissolution parameters of nickel matte in dilute sulfuric...

The toxicities of corrosion inhibitors were evaluated by the method of Quantitative Structure Activity Relationships (QSARs) and the results show that Dibenzyldithiocarbamic Acid Zinc Salt (ZBTC) is a low-toxicity corrosion inhibitor. The film of ZBTC was fabricated on a copper surface by self-a...

Phytoremediation is considered an ecologically beneficial technique for removing arsenic from aquatic environments but studies on the mechanisms of tolerance to this pollutant, when present in the form of arsenite (AsIII) still need to be performed. Thus, in order to evaluate the potential of Pi...

The indirect photocatalytic reduction of arsenate to arsenite in aqueous solution with titanium dioxide (TiO2) was investigated with various hole scavengers such as methanol, ethanol, 2-propanol, formaldehyde, acetone, formic acid and acetic acid. Although the direct photocatalytic reduction of ...

Arsenic contamination has threatened water safety due to its high toxicity and carcinogenicity. Therefore, it is urgent and significant to develop simple and effective approach for dearsenification of drinking water. In present study, Zn/Ce bimetallic oxide particles of various atomic ratios wer...

ABSTRACTIn the present study, the Miscanthus biochar was modified with amorphous iron (hydr)oxide to remove arsenite. The kinetic study indicated the chemical adsorption of arsenite on the iron-modified biochar. Additionally, the iron-modified biochar exhibited similar or higher adsorption of ar...

Rapid removal of the Acid Orange 7 (AO7) from aqueous solutions using natural pumice (NP) and Fe-coated pumice (Fe-CP) as low-cost adsorbents was well investigated and elucidated. The impact of several influential parameters such as initial pH, initial AO7 concentration and contact time on the a...

Ceramic ring and pumice stone were used as a support matrix for the enhancement of biohydrogen production in immobilized cell culture systems. The reactors were continuously operated for the hydrogen fermentation using sucrose as the major carbon source at varying hydraulic retention times (HRT)...

The objective of this study is the investigation of formaldehyde degradation in a bioreactor with pumice stone as a support. The reactor was tested at different synthetic wastewater concentrations with total COD of 500, 1000 and 1500 mg/L, respectively, at 24 h hydraulic retention time. The effe...
