We describe a pretreatment method before determining the total fluoride in solutions containing tetrafluoroborate ion (BF(4)(-)) with ion-selective electrodes (ISEs). BF(4)(-) was quantitatively converted to free fluoride by reacting with aluminum ions. The total fluoride concentration was then determined by ISE analysis without preliminary steam distillation using a tartrate- and tris(hydroxym...
Textile dyeing is considered to be one of the major industrial sources of high rates of organic and aromatic compounds. Conversely, these compounds have become a significant environmental problem. Many methods have been investigated for color removal from dye-containing wastewater. In this research, the efficiency of the electrocoagulation (EC) process with aluminum electrodes in the removal of...
Removal of algae in the reservoir water was studied by electroflocculation using a bipolar cell with aluminum electrodes and flocculation by treatment with commercial alum. Comparison of both the methods is discussed.
groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. this study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...
Introduction: By appropriate method can be recycled more than 95 percent effluent backwashing the filter. This study aimed to examine the efficiency of the electrocoagulation process on turbidity and suspended solids removal from backwash effluent of rapid sand filter of water treatment plants No 1 in Karaj. Methods: This bench-scale experimental study was carried out on the samples of b...
In this paper, the structure of SAW has been studied. In previous work in SAW, materials such as lithium niobium, lithium tantalite and gallium nitride were used in the structure of SAW, and thus had a low operating frequency and the highest reported operating frequency was about 4 GHz. In this paper, aluminum nitride and gallium nitride in the SAW structure are used in combination. The electro...
application of electrocoagulation process for reactive red 198 dye removal from the aqueous solution
abstract background and purpose:the main objectives of this research were to evaluating the application of electrocoagulation process for 198 dye from the aqueous phase and determining the optimum operating conditions to the dye removal using aluminum and iron electrodes. materials and methods:the present study was conducted in bench-scale. the spectrophotometer dr 5000 was used to determine th...
The goal of this study was to develop a rechargeable aluminum–air battery with high capacity and longterm durability in charge–discharge electrochemical reactions. We used aluminum terephthalate as a metal–organic framework (MOF) material for the air cathode and 1-ethyl-3-methylimidazolium chloride as an ionic liquid electrolyte. When we used aluminum terephthalate as an air cathode material, t...
