Evaluating the possibility of color treatment of Tarcon Blue 2BLN dye by coagulating materials PGa21Ca, polyaluminium chloride, iron (II) sulfate heptahydrate and aluminium sulfate octadecahydrate

The 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...

Coagulation of arsenic adsorbed ferrihydrite with the use of polyaluminium chloride (PAC) or polyferric sulfate (PFS)

Ferrihydrite is effective in arsenic removal because of the considerable amount of active hydroxyl groups. Solid–liquid separation of the arsenic adsorbed ferrihydrite from aqueous solution is important for the arsenic treatment technology. Coagulation is a promising process for ferrihydrite separation. Effects of different coagulants on arsenic adsorbed ferrihydrite settlement were investigate...

رنگرزی نخ خامه پشمی با گل زعفران، بررسی تأثیر دندانه و اسید

This research work involves the dyeing of wool yarns with saffron petals as a source for green color. At first step woolen pile yarns treated with four different mordents, namely: tin chloride, copper sulfate, aluminum sulfate and iron(II) sulfate in acidic condition using acetic, oxalic, citric and lactic acids respectively. In this study the possibility of using saffron petals as a natural dy...
