“…The higher pH of the solution shows more efficiency in desorption of procion red MX-5B dye. The surface properties of alumina and the functional groups on the adsorbent are affected by pH solution [12,15,24]. The alumina has a point of zero charge (pHpzc) of 7.4.…”

“…The alumina has a point of zero charge (pHpzc) of 7.4. In solution with pH  pHpzc, alumina would have negative charge [11,15,25]. Thus, in alkaline solution, there is electrostatic repulsion between anion of dye with the negatively charged of the surface of alumina [15].…”

“…Alumina is also known to have pore system and active sites on its surface. Alumina was reported by several researchers for having the ability to adsorb orange G, yellow monochlorotriazine, and yellow dichlorotriazinecolor black G [5,[15][16]. Surface modification of adsorbent using alumina was expected to increase the adsorption capacity as shown by modification of bentonite-alumina [17], alumina-chitosan [18], and activated carbonalumina [19][20].…”

“…Nano adsorbents offer considerable decontamination potential due to their unique properties as nanoscale materials [10]. ey are known for their high surface area to volume ratio, small size, high capacity for regeneration, and ability to make available a large number of reactive sites [11]. Nanoadsorbents based on inorganic iron and aluminum nanomaterials [12][13][14][15][16] were the first studied nanoadsorbents due to their low cost and high pollutant removal efficiency.…”

In this work, a mesoporous nanocomposite composed of nanogibbsite (α-Al(OH)3) and nanosilica was prepared. Gibbsite nanoparticles (GNPs) with a crystal size of ≈38 nm were prepared from Al-dross industrial waste products in an acidic environment at 100°C. Nanosilica (NS) with a crystal size of ≈13 nm was prepared from sodium silicate using dilute hydrochloric acid. The deposition of nanosilica onto gibbsite particles was investigated. The mesoporous silica-gibbsite (NSG) nanocomposite was examined by evaluating its ability to adsorb the toxic anionic dye Eriochrome black T (EBT) from aqueous solution. The compositional and morphological properties of NSG nanocomposites were studied by means of the FTIR spectroscopy, X-ray fluorescence (XRF), XRD, SEM, and TEM techniques. The effect of dye concentration, pH, adsorbent dose, contact time, and temperature was investigated. The sorption models, the isotherms, and the thermodynamic parameters ΔHo, ΔGo, and ΔSo were evaluated. The N2 adsorption-desorption isotherms revealed that mixing the two prepared materials (NS and GNPs) to form the NSG nanocomposite resulted in good properties (a surface area of 62.34 m2·g−1, a pore radius of 22.717 nm, and a pore volume of 0.7081 cm3·g−1). The results show that the prepared NSG nanocomposite has a remarkable ability to adsorb toxic anionic dyes.

“…Orange G is a monoazo, negatively charged dye and widely used in printing and textile industries. The dye is reported to be highly toxic to human beings due to its carcinogenic and teratogenic nature [6]. In the present investigation, activated carbon was prepared from an agricultural waste, kuppaimeni leaf (KPL), karuvelai leaf (KVL) and bottle gourd shell (BGS) powders to use them as adsorbents for the adsorptive removal of a toxic dye, Orange G (OG) from its aqueous solutions.…”

We prepared activated carbon from an agricultural waste, kuppaimeni leaf (KPL, Acalypha Indica), karuvelai leaf (KVL, Prosopis juliflora) and bottle gourd shell (BGS, Lagenaria siceraria) powders to utilize them as adsorbents for the removal of an anionic dye, Orange G (OG) from aqueous solutions. The effect of various parameters such as initial dye concentration, time, pH and temperature were investigated in the adsorption studies of Orange G dye removal. The experimental values were in good agreement with the model predicted values. Adsorption data were modeled using Freundlich and Langmuir adsorption isotherms. The adsorption of Orange G dye by activated carbon obeys Langmuir isotherm. Adsorption kinetic data were also tested using pseudo-zero, first and second-order kinetics. Kinetic studies revealed that the adsorption follows pseudo-second-order reaction. SEM results showed that the surface of the activated carbon was turned from dark to light colour after dye adsorption.
