Kinetic Study and Equilibrium Isotherm Analysis of Nickel (II) Adsorption onto Alginate-SBA-15 Nanocomposite
The present work was undertaken to evaluate the feasibility of nickel (II) removal from aqueous solution by adsorption onto a biopolymer adsorbent. The adsorbent was prepared using modification of mesoporous silicate SBA-15 with alginate biopolymer (alginateSBA-15) by encapsulation method. Morphological structure of the obtained nanocomposite adsorbent was characterized by XRD, scanning electro...
متن کاملAdsorption of Metallic Ions onto Chitosan: Equilibrium and Kinetic Studies
Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions. The adsorption capacity of chitosan depends on a number of parameters: deacetylati...
متن کاملFurther Study of Adsorption of Crude Oils onto Acetylated Corn Silk and its Kinetics and Equilibrium Isotherm
Oil spills from tanker or oil well have detrimental effects on environment and economy. One of the most economical and efficient methods for oil spill clean-up is mechanical extraction by sorbents which are not only the safest methods but also the least expensive of spill control. The potential use of agricultural by-products such as corn silk for adsorbent of crude oil from water systems was p...
متن کاملEquilibrium Modeling and Kinetic Studies on the Adsorption of Basic Dye by a Low Cost Adsorbent
An agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. The physical properties of the developedadsorbent were characterized using FTIR. The study was realized using batch experiments. The effectsof contact time, pH, initial dye concentration, biosorbent dose and temperature were investigate...
متن کاملKinetic isotope effect on the proton-transfer in indigo carmine
We have found that photo-excited indigo carmine causes stepwise proton transfer to generate monoalcohol intermediate, which immediately returns to the parent molecule [I. Iwakura, A. Yabushita, T. Kobayashi, Chem. Lett. 38 (2009) 1020]. The kinetic isotope effect in the proton transfer of this system has been studied by direct observation of the real-time molecular vibrational amplitude during ...
