Pure Aqueous Solution

The development of highly selective and sensitive chemosensors for Al3+ detection in pure aqueous solution is still a significant challenge. In this work, a novel water-soluble polymer PEGBAB based on salicylidene Schiff base has been designed and synthesized as a turn-on fluorescent chemosensor for the detection of Al3+ in 100% aqueous solution. PEGBAB exhibited high sensitivity and selectivity to Al3+ over other competitive metal ions with the detection limit as low as 4.05 × 10−9 M. PEGBAB displayed high selectivity to Al3+ in the pH range of 5–10. The fluorescence response of PEGBAB to Al3+ was reversible in the presence of ethylenediaminetetraacetic acid (EDTA). Based on the fluorescence response, an INHIBIT logic gate was constructed with Al3+ and EDTA as two inputs. Moreover, test strips based on PEGBAB were fabricated facilely for convenient on-site detection of Al3+.

Hydrophobically Associating

The effects of Na+, Ca2+, and Mg2+ on hydrophobically associating water-soluble polymers (HAWP) were studied in this paper.Their decreased viscosity in aqueous solution at different salt concentrations were measured and the corresponding microstructure by Atomic Force Microscopy (AFM) were determined. The results show that the destructive microstrucure was the intrinsic reason for the decresed viscosity. Among the three salt aqueous solutins, CaCl2 has the highest strong destructive capability to the microstucute of HAWP.
