Doxorubicin is a planar aromatic molecule and it is commonly used in cancer chemotherapy. In this study, we compared nanostructured electrodes with gold nanocolumns and flat gold electrodes by measurements with doxorubicin. Nanostructured electrodes were fabricated by electrochemical anodic oxidation when the aluminium layer was transformed to the porous alumina layer. Then gold material was de...
Background & Aims of the Study: Discharge of textile industry colored wastewater without enough treatment into natural water resources cause serious pollution. Most of the conventional wastewater treatment methods are not effective enough to remove these dyes from wastewater. In this study, efficiency of electrocoagulation process with iron electrodes for treatment of Reactive Yellow 14 dye...
Attention is devoted to the role of chelating agents in the treatment of aluminium related diseases. In fact, in spite of the efforts that have drastically reduced the occurrence of aluminium dialysis diseases, they so far constitute a cause of great medical concern. The use of chelating agents for iron and aluminium in different clinical applications has found increasing attention in the last ...
In the present study different combinations of Al and Fe electrodes are used for improving treatment efficiency in electrocoagulation (EC) process to purify domestic wastewater. Various factors be studied assessment COD removal form pH (3–9), time (10–60 min), density current (9.0–40 A/m2). Depending on influencing factor Al–Al Fe–Fe able minimize percentage up 85.0 % 90% respectively...
Background and Objective: Electrochemical methods as one of the advanced oxidation processes (AOPs), have been applied effectively to degrade recalcitrant organics in aqueous solutions. In the present work, the performance of electro-Fenton (EF) method using iron electrodes on the degradation of phenol was studied. Materials and Methods: In this study, a lab-scale EF batch reactor equipped with...
In the conducted investigations, aluminium dross, i.e. solid waste formed in the production and recycling of aluminium, was used as one of the basic raw materials to obtain a material characterised by insulating and exothermic properties, applied to heat riser heads in the process of iron or steel casting. The product was obtained by filtrating the slurry. In the raw mix, aluminium dross played...
In this study, the electrocoagulation process was evaluated as a pretreatment process for olive mill wastewaters. Aluminium (Al) and iron (Fe) electrodes, several contact times and 0.5, 1 and 2 A currents were used to compare chemical oxygen demand (COD) removal efficiencies for each case. The optimum contact time and current were 45 minutes and 1 A, respectively, which resulted in a COD remova...
Dialysis is one of the effective methods which has been used since 1955 for the treatment of patients suffering from renal failure( more often of its chronic type). The dialysis results in the elimination of waste materials like urea and creatinine from the body, on the other hand, it can affect the serum contamination of the dialysis fluid. Aluminium is one of trace elements which its serum le...
Background and purpose: Imidacloprid (IM) is a systemic insecticide that is widely used to control a large number of pests in agriculture. It has toxic effects, therefore, it should be removed using appropriate methods. The aim of this study was to evaluate the efficiency of electrochemical degradation process to remove IM from aqueous solutions. Materials and methods: In this experiment, a gl...
abstract background: heavy metals in industrial wastewater especially chromium (vi) are considered as the main environmental pollutants. methods: electrochemical cell made of plexiglass with a volume of 1.95 lit was used. iron and graphite electrodes, electricity conductor, each with dimensions of 0.1×3×10 cm (width×length×height) were designed and built. tests were carried out in various condi...
