A potential low cost adsorbent for the removal of cationic dyes from aqueous solutions

Removal of perilous dyes from aqueous solutions with CuO adsorbent

Coal Ash as a Low Cost Adsorbent for the Removal of Xylenol Orange from Aqueous Solution

The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...

Column operation studies for the removal of dyes and phenols using a low cost adsorbent

Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

The Use of Corn cob Micro Powder as a Low Cost Adsorbent, for the Removal of Co2+Ion from Aqueous Solutions and from the View Point Thermodynamics

Corn cob as a low cost adsorbent was used in the present work for the removal of toxic heavy metal Co2+ from aqueous solutions. Bath experiments were used to determine the best adsorption conditions. The equilibrium adsorption level was determined as a function of solution pH, temperature (T), contact time (tc), initial adsorbate concentration, and adsorbent dosage. Effective removal of metal i...

Removal of Reactive Red 120 from Aqueous Solutions Using Albizia lebbeck Fruit (Pod) Partical as a Low Cost Adsorbent

Synthetic dyes are using extensively in various industries such as textile, leather tanning, plastic, pulp and paper. Since this dyes are mainly toxic and even carcinogenic, discharging dye containing wastewater into the environment generates serious environmental and health consequences. Therefore, in this research investigated and evaluated the removal effect of Reactive Red 120 (RR 120) from...
