In this paper, a new fluorescent probe has been synthesized and applied as "off-on" sensor for the detection of Al(3+) with a high sensitivity and excellent selectivity in aqueous media. The sensor was easily prepared by one step reaction between rhodamine B hydrazide and pyridoxal hydrochloride named RBP. The structure of the sensor has been characterized(More)
A novel carboxylate-functionalized adsorbent (CNM) based on cellulose nanocrystals (CNCs) was prepared and adsorptive removal of multiple cationic dyes (crystal violet, methylene blue, malachite green and basic fuchsin) were investigated. The maximum cationic dyes uptakes ranged from 30.0 to 348.9mgg(-1) following the order of: CNM>CNCs>raw cellulose.(More)
4,5-Bis(hydroxymethyl) acridine (sensor 1) has been discovered and synthesized as a simple-structured Pd(2+) fluorescent probe. Sensor 1 showed highly selective recognition toward Pd(2+) over other examined metal ions in aqueous solution. Under the optimized condition, fluorescence intensity was linearly proportional to the concentration of Pd(2+) in the(More)
With rapid development of processors, multi-core processors occupied the main market due to their superior performance and power characteristics. Threads run concurrently on a multi-core processor and share the processor’s the second-level (L2) cache. Cache allocation and sharing is critical to the effective utilization of multi-core(More)
We designed and synthesized a mono-Schiff-base fluorescent probe (Probe 1) based on a boron-dipyrromethene (BODIPY) dye. By investigating the recognition of Au(3+) through an irreversible C=N bond hydrolysis reaction, Probe 1 exhibited higher properties such as acting as a "naked eye" probe, stability to pH, fast-response of 90s, a lower detection limit of(More)
A dual-function optical chemosensor (RBF) was designed and easily synthesized by condensation reaction of 5-Hydroxymethylfurfural and rhodamine B hydrazide. RBF exhibited highly sensitive, highly selective and quick response to acidic pH. The fluorescence intensity of RBF exhibited a more than 41-fold increase within the pH range from 7.50 to 3.73 with a(More)
Cellulose modified with maleic (M) and phthalic (P) anhydride, to be named CMA and CPA, were tested as feasible adsorbents for the removal of malachite green from aqueous solution. At the same time, the uptake ability of natural cellulose was also studied for comparison. The structure of material was characterized by FT-IR and XRD. The effects of solution(More)
