Synthesis, characterization and analytical applications of a new composite cation exchanger cellulose acetate-Zr(IV) molybdophosphate

Pectin–cerium (IV) tungstate nanocomposite and its adsorptional activity for removal of methylene blue dye

“…The composite ion exchangers have been used in environmental remediation because of their selectivity, specificity and wide range of applicability (Khan and Khan 2010;Vatutsina et al 2007). The attempt has been made by various researches to improve the chemical, mechanical, thermal properties and selectivity of composite ion exchangers for certain heavy metal ions (Islam and Patel 2008;Nabi and Naushad 2008;Bushra et al 2012;Nabi et al 2011;Khan and Paquiza 2011). The composite ion exchangers have been used effectively in different fields such as ion selective electrodes, catalysis, hydrometallurgy, bimolecular separations, chromatography and environmental science engineering (Hassan et al 2001;Nabi et al 2010;Arrad and Sasson 1989).…”

Use of cellulose acetate–tin (lV) phosphate composite (CA/TPC) in highly effective removal and recovery of heavy metal ions

“…The absorption band at 1,710 cm -1 was aroused due to the carbonyl group of cellulose acetate part. The broad peak at 1,020 cm -1 was assigned to the presence of PO 4 3-and H 2 PO 4 -groups, respectively [35]. The absorption band at 470 cm -1 may be due to the superposition of metal-oxygen stretching vibrations suggested the combination between cellulose acetate and tin (IV) phosphate [32].…”

“…Organic-inorganic hybrid composite materials, due to its exceptional chemical, mechanical and thermal properties as compared to pure inorganic and organic materials, have attracted a great attention in scientific community. Converting the organic and inorganic materials into an organic-inorganic hybrid composite with better properties is an economic method which has been a hot topic [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. The organic-inorganic hybrid composite minimizes the limitations of organic and inorganic materials by modifying individual properties of each of the organic and inorganic materials.…”

Development of Solid-state Reference Electrode Based on Sodium Polyanethol Sulfonate Immobilised on Cellulose Acetate

“…15,16,47 The porous form of cellulose acetate membrane also contributed to the onset of the process of leaching of SPS salts from the cellulose acetate matrix. [29][30][31][32][33][34] From Figure 5, it can be observed that the stability of the solidstate reference electrode was initially low and started to degrade after 35 h.…”

“…In addition to these, cellulose acetate membrane has a porous physical structure, which helps in the movement of both ions and water molecules toward the sample or in the opposite direction. [31][32][33][34] As seen in Table 2, the concentration of SPS salt immobilised onto the cellulose acetate membrane gives an impression of the response slope when tested at various concentrations of KCl solution and pH of the solution when the solid-state reference electrode was coupled with the standard Ag/AgCl reference electrode with double junction type. In this work, the solid-state reference electrode functioned as a working electrode.…”
