Nickel-iron layered double hydroxide (LDH): Textural properties upon hydrothermal treatments and application on dye sorption

The effect of hydrothermal treatment temperature on the kinetics of dye removal has been explored. It was found that the percentage color removal increases with increasing hydrothermal treatment temperature up to 140 °C and aging time up to 4 days. Furthermore, the color removal decreases with increasing hydrothermal treatment temperature up to 140-180 °C and prolonged aging time.
