Congo red removal using oxidized multiwalled carbon nanotubes: kinetic and isotherm study

Synthesis of porous starch xerogels modified with mercaptosuccinic acid to remove hazardous gardenia yellow

“…The results indicated that the equilibrium capacity and the percentage removal of GY exhibited an opposite change tendency with the increase in C 0 . Although the equilibrium adsorption capacity of GY increased with the increase in C 0 since the resistance to the uptake of GY from the solutions decreased with the increase in GY concentration [8], the GY per- centage removal decreased significantly (from 90% to 36%) with increasing C 0 of GY from 100 to 400 mg L −1 .…”

“…Among the various techniques, adsorption appeared to be an attractive and acceptable approach for the removal of dyes due to its low cost, ease of handling, high efficiency and no threat of secondary contamination [5][6][7]. The common adsorbents used for dyes removal primarily included oxidized multiwalled carbon nanotubes [8][9][10], graphene oxide (GO) [11][12][13][14], biomass sources [15][16][17], activated carbons [18][19][20], and so on. However, efforts would be still needed for the development of new potentials and effective adsorbents.…”

Highly efficient simultaneous ultrasonic assisted adsorption of brilliant green and eosin B onto ZnS nanoparticles loaded activated carbon: Artificial neural network modeling and central composite design optimization

“…Dyes enter to organism life via pulmonary and digestive system (water or food) [8,9] that cause requirement of preliminary clean up procedure before their entrance to water bodies.…”

Application of least squares support vector regression and linear multiple regression for modeling removal of methyl orange onto tin oxide nanoparticles loaded on activated carbon and activated carbon prepared from Pistacia atlantica wood

“…Support vector regression (SVR) and support vector classification (SVC) are the applications of support vector machine (SVM) [31] which is a time-consuming process. This limitation is overcome by the least squares support vector machine (LSSVM) as the modified version of SVM [39] which is a time-consuming process.…”

“…In addition to the above mentioned properties, combination of nanoparticles (loaded on AC) help the researchers to remove the high quantity of various dyes in a short time [31]. Nanomaterials [32] with unique physico chemical properties (smaller size, higher surface area, and inter particle interaction affinity) are preferred over other adsorbents for noxious dye removal.…”
