The blending technology makes it possible to rebuild high molecular weights of partial polymers, thus to improve the product performance together with improvement of specific properties. Pure Carboxymethylcellulose (CMC) film and CMC (80%) doped Polyacrylic Acid (PAA) (20%) films were prepared by using a solution casting method. The influence of PAA polymer addition on the structural and optical properties of CMC polymer was investigated systematically. From X-ray diffraction patterns, adding a polymer PAA to a polymer CMC can lead to the appearance of peaks in polymer blend. FESEM image for CMC/ PAA film showed the formation of small spherical grains for PAA into CMC that insured the existence of some peaks in XRD pattern of PAA in CMC film which means the improvement of the microstructure of the polymer matrix. No chemical interactions were observed between CMC and PAA polymers from results of FTIR spectrum, so that incorporation of PAA into CMC polymer will results physical reaction only. The results of the UV spectrum have shown that the absorbance, absorption coefficient, extinction coefficient, refractive index, real and imaginary dielectric constants were increased in blend polymer compared with the pure polymer. The energy gap and transmittance of blend polymer compared with the pure polymer were reduced.

“…The absorbance of AO dye reduces when PVA is added from 0.80 at AO dye solution to be 0.1 and 0.24 at 6 ml and 12 ml respectively, but it increases when the volume ratio of AO dye solution is increased to 0.49 for 18ml and declines for 24-and 30-ml volume ratios owing to form dye aggregation, which inhibits the intensity of the absorption spectra (0.35, 0.33). The transitions are π→π* due to chromophore groups (the extended conjugated double bond [17,18]. The increase in the volume ratio of AO inside the polymer matrix increases the radiation absorbing species, increasing in absorbance.…”

Polyvinyl Alcohol (PVA) polymer/ Acridine Orange (AO) dye films prepared via casting technique at room temperature. The effect of adding (Acridine Orange (AO) dye solution, Magnesium Oxide (MgO), and Aluminum Oxide (Al2O3) NPs) to the PVA polymer matrix were studied on the absorption spectra. The effect of AO addition on the absorption spectrum of PVA film is occurrence blue shift (5nm) from 280nm to 275 nm in the PVA and red shift (10nm) from 490nm to be 500 nm for AO maximum absorbance wavelength. The absorbance of AO dye decreases when adding PVA, but increases When the volume ratio of AO dye solution is increased to 0.49 for 18ml, the volume ratio of AO dye solution decreases for 24- and 30-ml volume ratios. Adding NPs led to enhancing the photophysical properties of polymer composite, noted that absorbance of adding alumina nanoparticles more than it is in the case of adding magnesia nanoparticles. Also, there is a 10 nm red shift in AO and a 5 nm blue shift in AO when they are added to the polymer matrix filled with MgO and Al2O3 NPs.

“…Once CIP was added into the receptor, which enhanced the intensity of the fluorescence (Figure 6b), a bathochromic shift was observed (Figure 6a). This shift may be due to the addition of CIP, which affects or reduces the energy gap between the HOMO (highly occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) [48]. Moreover, the 1 H-NMR spectra of both MOF and C-MOF-808 were carried out, and the results are given in Figure 5.…”

Ciprofloxacin (CIP) is a commonly used antibiotic for the treatment of infectious diseases in humans and as a prophylactic agent in the livestock industry, leading to the environmental discharge of significant amounts of CIP. CIP is stable in aquatic systems leading to its pseudo-persistence. Constant exposure to these antibiotics results in the generation of antibiotic-resistant pathogens and potential toxicity/hypersensitivity in humans. Therefore, it is necessary to develop a convenient, rapid, and cost-effective method for the monitoring of ciprofloxacin in environmental samples. Rhodamine-based fluorescent receptors have the limitation of aqueous solubility. Therefore, in order to overcome this drawback, we designed a novel fluorescent receptor based on a zirconium-based metal organic framework (MOF-808). The precursor, MOF-808, was synthesized and functionalized by using sodium citrate to obtain a receptor called C-MOF-808. The C-MOF-808 was structurally characterized by XRD and spectroscopic analyses. Thus, this synthesized receptor can be used for the fluorescent detection of CIP in aqueous media with a detection limit of 9.4 µM. The detection phenomena of the receptor were studied by absorption as well as fluorescent spectra. The binding behavior of CIP with the receptor was studied by FT-IR and 1H-NMR analyses, and a binding mechanism is proposed.
