Preparation and Characterization of Nano-lignin Biomaterial to Remove Basic Red 2 dye from aqueous solutions
The present study prepares alkali lignin (AL) via acidification of black liquor, obtained from a pulp and paper factory. The average molecular weight of AL (equal to 2,530 g/mol) has been determined with gel permeation chromatography. AL has been modified by ethylene glycol, while lignin nanoparticles (LN) has been prepared through acid precipitation technology, their size being assessed by mea...

متن کاملZinc Electrodeposition from Acetate Solutions
he electrodeposition of zinc on iron and steel for protection T against corrosion was first proposed in 1840. The combination of aesthetic appeal and protection thus provided has established bright zinc plating as an important process in modern industry. In today's technology, zinc is preferably deposited from acid-type electrolytes, especially chloride, as an alternative to those based on cyan...
متن کاملThe Color Removal of Dye-Containing Wastewater by Cerium (IV) Sulfate from Aqueous Solutions
In this study a giant reagent such as Ce (SO4 )2 was used for removing different initial dye concentration (10-1000 mg/l) of reactive red 31 (R.R31) less than two minutes in a laboratory scale whereas the percent of dye removal efficiency was %99.9. The Langmuir, Freundlich and Tempkin adsorption models were applied to describe the equilibrium isotherms. The Langmuir model agreed very well with...
متن کاملRates of Metal Electrodeposition from Aqueous Solutions in the Presence of Chelating Agents
The rates of Cu deposition from aqueous solutions containing chelating agents, such as citric acid, nitrilotriacetic acid (NTA), and ethylenediaminetetraacetic acid (EDTA), in an electrochemical membrane cell were measured. An equimolar solution of chelating agents and metals was examined. The iridium oxide and Pt coated on titanium electrodes were used as the anode and cathode, respectively. T...
