Micronized and nano-copper (Cu)-based and arsenic and chromium-free systems have received much attention for wood protection in recent years. Because they have different fixation, and micro-distribution properties, such copper systems may be more or less subject to release using known remediation methods than soluble forms of Cu. This study evaluated Cu recovery from wood treated with micronize...

Abstract: Heavy metal contamination of drinking water poses serious threat to public health and ecosystems. Chronic exposure to such metal contamination can lead to various health problems including nerve and organ damages. Thus, removal of heavy toxic metals from the contaminated water supply is a critical issue of water quality management. Naturally-occurring resources have been attractive ca...

In this study, three agro-waste materials were used as biosorbents for removal of copper (Cu) from water. This work aims to optimise conditions for preparation of these materials to obtain maximum Cu adsorption capacity. The optimal conditions were determined in terms of Cu removal efficiency and/or energy consumption. The results indicate that banana peels dried at 120°C for 2h and ground into...

The simultaneous decomplexation of Cu-EDTA and electrodeposition recovery of Cu(2+) ions was attempted in a photoelectrocatalytic (PEC) system using TiO2/Ti as the anode and stainless steel as the cathode. At a current density of 0.5 mA/cm(2), removal efficiencies of 0.05 mM Cu-EDTA by photocatalysis, electrooxidation, and PEC processes were determined to be 15, 43, and 72% at 3 h, respectively...

Mandarin peels were investigated for the removal of copper ions from ethanol fuel. Infrared spectroscopy and thermogravimetric analysis were used for elucidating possible functional groups responsible for the adsorption of Cu(II) from ethanol. The influence of parameters such as the mass of the adsorbent, sample pH, stirring time, and initial copper(II) concentration was investigated using mult...

Alginate blended with cellulose nanocrystals (CNC), nanofibers (CNF), and tri-carboxylate (TPC-CNF) prepared encapsulated in the form of microcapsules (bio-polymeric beads). The cellulosic nanomaterials that used this study were investigated as for wastewater treatment applications. Batch experiments performed to removal copper, lead, magnesium, iron from aqueous solutions by beads. effects sor...
