The removal of crystal violet from aqueous solution by NiFe2O4 magnetic nanoparticles treated with sodium dodecyl sulfate was investigated. The modified magnetic nanoparticles were prepared by chemical reaction of a mixture of Ni+2 and Fe+3 ions mixture in aqueous solution at the presence of ammonia and then sodium dodecyl sulfate was utilized as an ionic surfactant to modified the obtained mag...

Graphene oxide (GO) is a highly effective adsorbent, and its absorbing capability is further enhanced through its in situ reduction with sodium hydrosulfite as the reductant. Acridine orange is the selected target to eliminate with GO as the adsorbent. Under identical conditions, GO without the in situ reduction showed a maximum adsorption capacity of 1.4 g g(-1), and GO with the in situ reduct...

Fast development of the coalbed natural gas (CBNG) industry in many parts of the western U.S. has resulted in the co-production of potentially salinesodic waters, hereafter referred to as CBNG water. Management of CBNG water is a major environmental challenge because of its quantity and quality. In this study, the potential utilization of calcium (Ca)-rich natural zeolites were examined for rem...

Adsorption of sodium diclofenac was investigated in the presence of sucralfate--a cytoprotective agent preventing gastropathy, adverse effect of diclofenac. Evaluation of adsorption was performed by means of a static method in vitro taking into account pH of the environment, temperature, concentration of the investigated agents and the form of sucralfate. Findings obtained prove that sodium dic...

Interactions of oppositely charged macroions in aqueous solution give rise to intriguing aggregation phenomena, resulting in finite-size, long-lived clusters, characterized by a quite narrow size distribution. Particularly, the adsorption of highly charged linear polyelectrolytes on oppositely charged colloidal particles is strongly correlated and some short-range order arises from competing el...

We have developed a united atom force field able to accurately describe the adsorption properties of linear alkanes in the sodium form of FAU-type zeolites. This force field successfully reproduces experimental adsorption properties of n-alkanes over a wide range of sodium cation densities, temperatures, and pressures. The force field reproduces the sodium positions in dehydrated FAU-type zeoli...

Tumkur Taluk is located in the southeastern corner of Karnataka state between 13 degrees 06'30'' to 13 degrees 31' 00'' North latitude and 76 degrees 59' 00'' to 77 degrees 19' 00'' East Longitude. The Taluk spreads over an area of 1043 sq.km falling within the semiarid region and frequently facing water scarcity as well as quality problems. The major sources of employment are agriculture, hort...

Abstract To obtain the similar materials with specific physical and mechanical parameters adsorption desorption indexes used in coal gas outburst simulation tests, pulverized was selected as aggregate, sodium humate cementing agent river sand auxiliary materials. Based on this, orthogonal tests 6 factors 5 levels were designed, of weighing, uniaxial compression, firmness, carried out. The such ...

Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was employed to study the sorption behaviors of cellulases on microcrystalline celluloses and hardwood pulp. The adsorption and recovery of cellulases from Aspergillus niger and Trichoderma reesei were investigated at 25 °C. Cellulase recovery was conducted by rinsing adsorbed enzymes with sodium acetate buffer, Milli-Q water,...
