چکیده

Biosorption of chromium (Cr(VI)) is studied by using raw (chemically not modified) Moringa (Moringa Oleifera) leaf powder without any pretreatment. Cr(VI) one the potentially harmful heavy metals found in industrial wastewater. In powder, presence a significant amount organic acids form source for biosorption Cr(VI). The concentration feed solution varied and different dosages proposed biosorbent are used to study its efficiency removal from 1 ppm 20 while 0.5 g 2.5 g. equilibrium time adsorption observed vary between half an hour 90 min. metal 30% 90% which achievement compared other conventional methods either energy-intensive or cost effective. experimental results modeled Langmuir, Freundlich Redlich–Peterson isotherms. attributed chelating effect carboxylate hydroxyl groups present moringa leaves confirmed FTIR analysis. Further molecular docking simulations performed confirm binding speculated sites within leaves. Untreated green as this leads sustainable cheaper option treating wastewater containing

Improving Removal of Nickel from Wastewater using Palm Leaf Ash as a Biosorbent

Nickel (Ni) as a heavy metal due to its toxicity should be removed from wastewater and aquatic environments  using  efficient  technology.  The  aim  of this  study  was  to  remove  Ni  from  an aqueous  solution  using  palm  leaf  ash  produced  in  a  furnace.  To  do  so,  kinetic  and thermodynamic experiments were conducted on the adsorption process. Moreover, the effect of time, pH, ads...

Equilibrium and kinetic study on chromium (VI) removal from simulated waste water using gooseberry seeds as a novel biosorbent

Gooseberry seed (Phyllanthus acidus) was used as an adsorbent to determine its feasibility for the removal of Cr(VI). Various parameters such as pH, temperature, contact time, initial metal concentration and adsorbent dosage were investigated to determine the biosorption performance. Equilibrium was attained within 60 minutes and maximum removal of 96% was achieved under the optimum co...

REMOVAL OF ORGANIC DYES FROM CONTAMINATED WATER USING COFE2O4 /REDUCED GRAPHENE OXIDE NANOCOMPOSITE

Up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. Among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. Graphene, a new class of 2D carbonaceous material with atom thi...
