“…Huge content of contaminant in different industrial waste water via their following entrance to aqueous media led to serious the damaging their quality of in subsequently destroy health of living things [1][2][3]. Some of these contaminants due to their natural toxicity, carcinogenic or mutagenic property and also their high bioaccumulation efficiency received special attention even at very low concentrations [4][5][6].…”

In this study, ultrasound assisted dispersive solid-phase micro extraction combined with spectrophotometry (USA-DSPME-UV) method based on activated carbon modified with Fe2O3 nanoparticles (Fe2O3-NPs-AC) was developed for pre-concentration and determination of safranin O (SO). It is known that the efficiency of USA-DSPME-UV method may be affected by pH, amount of adsorbent, ultrasound time and eluent volume and the extent and magnitude of their contribution on response (in term of main and interaction part) was studied by using central composite design (CCD) and artificial neural network-genetic algorithms (ANN-GA). Accordingly by adjustment of experimental conditions suggested by ANN-GA at pH 6.5, 1.1mg of adsorbent, 10min ultrasound and 150μL of eluent volume led to achievement of best operation performance like low LOD (6.3ngmL(-1)) and LOQ (17.5ngmL(-1)) in the range of 25-3500ngmL(-1). In following stage, the SO content in real water and wastewater samples with recoveries between 93.27-99.41% with RSD lower than 3% was successfully determined.

“…It is worth noting that the MWCNT completely keeps its original structure after adsorption (Figure 7c) and desorption (Figure 7d), which is recognized to be responsible for its high cycling stability shown above. The adsorption mechanisms of MWCNTs towards dyes can be divided into nonspecific interactions and conditional attractive forces [46] . The attractive forces between dyes and the surfaces of MWCNTs may be the synergistic effects of van der Waals interactions, π‐π interactions, hydrogen bonding and electrostatic interactions [47–49] …”

Post‐processing methods have been widely reported as an effective method to purify and functionalize the surface of carbon nanotubes (CNTs). We used a new Co‐based coordination polymer (CP) as a catalyst precursor to synthesize multi‐walled CNTs (MWCNTs) by the chemical vapor deposition (CVD) method, and examined the use of acidification, carbonization and functionalization treatments in an attempt to achieve experimental conditions which efficiently functionalize the surface of MWCNTs. Our results indicate that post‐processing methods can efficiently tune the quality and purity of MWCNTs, and these methods play important roles in dye adsorption.

“…4 In the last decade, the use of CNTs for the removal of organic and inorganic pollutants has been investigated, and performances comparable to those of commercial adsorbents have been obtained. 5–8 Considering the relatively high cost of single-walled CNTs (SWCNTs), multi-walled CNTs (MWCNT) adsorbents may be more promising for practical use.…”

A CuI coordination polymer based on the N,N’-bis(3-pyridinecarboxamide)-1,4-butane (3-dpyb) ligand, namely [Cu(3-dpyb)0.5Cl], is hydrothermally synthesized and structurally characterized, and is used as a catalyst precursor to synthesize multi-walled carbon nanotubes. Interestingly, the as-grown multi-walled carbon nanotubes exhibit high performance in removing dyes from solution and can serve as a low-cost and fast adsorbent. In addition, the adsorption behavior of this new adsorbent fits well with the Freundlich isotherm and the pseudo-second-order kinetic model.
