Kinetic, thermodynamic and isotherm studies for acid blue 129 removal from liquids using copper oxide nanoparticle-modified activated carbon as a novel adsorbent

Microporous nanocrystalline NaA zeolite prepared by microwave assisted hydrothermal method and determination of kinetic, isotherm and thermodynamic parameters of the batch sorption of Ni (II)

“…There are several adsorbents such as sensors and electrochemical electrodes [14][15][16][17][18], bagasse fly ash [19,20], bottom ash [21,22], CNTs and MWCNTs [23][24][25][26][27][28][29][30], fix bed adsorbers [31], resins [32], nanoparticles [33][34][35][36][37][38][39], and rubber tire [40][41][42], these all and the previously developed adsorbents have various applications in many scientific and industrial fields, including wastewater purification, heavy metal ion removal and hazardous impurities.…”

Kinetics of the adsorption of Pb(II) ions from aqueous solutions by graphene oxide and thiol functionalized graphene oxide

“…It also does not result in the formation of any other harmful secondary pollutant [15]. So far, researchers have tested many different types of developed adsorbents such as carbon nanotubes [16][17][18][19][20][21][22][23], MWCNTs [24,25], nanoparticles and nanocomposites [26][27][28][29][30], rubber tire [31,32], and other low cost adsorbents [33][34][35][36][37][38] etc. are used for the removal of noxious impurities from the aqueous solution.…”

Synthesis of a novel ionic liquid modified copolymer hydrogel and its rapid removal of Cr (VI) from aqueous solution

“…When the adsorption equilibrium is reached, the increase of PAMDA dosage increases only the unoccupied surface areas in case of constant initial Cr (VI) concentration, but affects little on the total occupied surface areas. Naturally, the calculated adsorption capacity by using all the mass of adsorbent would be reduced [43], while the removal percentage keeps unchanged. Taking into consideration of the above factors, the optimum dosage of PAMDA for 50 mL of 100 mg L À1 Cr (VI) solution was chosen as 0.1 g for further experiments.…”
