“…Conversely, at pH = 11.00 surface of RPAL will be negatively charged, therefore, less interaction between RB and RPAL surface. Similar results for better sorption of RB in acidic media has been previously reported using different adsorbents such as Fe (III)-montmorillonite [16], chitosan-TiO 2 nanocomposite [17], and bottom ash [40].…”

“…Moreover, RB is extensively used in fabric and photochemical manufacturing. Nonetheless, RB has shown serious impacts on human health, especially when it gets in contact with skin and eyes causing discomfort, irritation, redness and blistering [ 14 , 15 , 16 , 17 , 18 ]. Removal of RB from wastewater has been done implementing various methods such as photo-degradation, nanofiltration and adsorption [ 19 , 20 , 21 , 22 ].…”

Adsorptive removal of rose bengal (RB) from contaminated water samples was approached using pineapple leaves (PAL). Three adsorbents were utilized for that purpose; raw pineapple leaves (RPAL) and the thermally activated bio-waste leaves at 250 and 500 °C. Two measures were executed to evaluate the functionality of exploited biomasses; percentage removal (%R) and adsorption capacity (qe). Face-centered central composite design (FCCCD) was conducted to experiment the influence of variables on the %R. Dose of PAL as adsorbent (AD), concentration of RB (DC), pH and contact time (CT), were the inspected factors. Existence of functional groups and formation of activated carbon was instigated employing Fourier-transform infrared (FT-IR) and Raman spectroscopies. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) analyses were used to explore surface features. Thermal behavior of adsorbents was studied using thermogravimetric analysis (TGA). The surface area and other surface structural properties were established using the Brunauer Emmett-Teller (BET) analysis. An amount of 92.53% of RB could be removed with an adsorption capacity of 58.8 mg/g using a combination of pH 5.00 ± 0.20, RPAL dose of 0.05 mg/50 mL, and 10-ppm RB for 180 min. Equilibrium studies divulge a favorable adsorption that follows the Freundlich isotherm. Pseudo-second-order model explains the observed adsorption kinetics.

Piezoelectric biosensors are a group of analytical devices working on a principle of affinity interaction recording. A piezoelectric platform or piezoelectric crystal is a sensor part working on the principle of oscillations change due to a mass bound on the piezoelectric crystal surface. In this review, biosensors having their surface modified with an antibody or antigen, with a molecularly imprinted polymer, with genetic information like single stranded DNA, and biosensors with bound receptors of organic of biochemical origin, are presented and discussed. The mentioned recognition parts are frequently combined with use of nanoparticles and applications in this way are also introduced. An overview of the current literature is given and the methods presented are commented upon.

Removal of Congo red (CR) dye from textile waste effluents is a challenging task. Therefore, a new molecularly imprinted polymer (MIP) based on Chitosan-TiO 2 nanocomposite (CTNC) was synthesized for the quantitative and selective removal of CR as a brand anionic dye from textile wastewaters. The physicochemical features and efficiency of the prepared MIPnanoparticles were investigated using various spectral techniques including FTIR, XRD, SEM, and N 2-adsorption-desorption isotherm. The mechanism and kinetics of CR removal were systematically investigated. The data fitted well into the Langmuir and the pseudo-second order models, revealing monolayer dye molecules formation. The prepared CTNC-MIPs was successfully applied to the elimination of CR, as a brand anionic dye, from highly polluted textile wastewaters. Moreover, the exceptionally high adsorption capacity, stability, and recyclability of the prepared CTNC-MIPs make it an excellent competitive to previously reported adsorbents.
