Abstract

Xuan-paper waste residue (XPWR) is an unfamiliar and unique solid waste in China, which caused serious environmental pollution and waste of resources. Therefore, it is extremely important to explore the characteristics of XPWR and its application. In this paper, XPWR was analyzed and used as a reinforcing filler to prepare red mud/waste polyethylene/Xuan-paper waste residue (RM/WPE/XPWR) composites by molding method at 160 °C with a pressure of 10 MPa for 5-10 min. There were about 27 wt% of mineral particles and 63 wt% of organic fibers in XPWR, indicating that XPWR can be used as a reinforcing filler. When 60 wt% of XPWR was added in RM/WPE, the bending strength reached 71.81 MPa, which surpassed 43.08 % than that of RM/WPE. Besides, the addition of XPWR increased the water absorption of the composites and helped to promote the crystallization of the composites. This work presented the characteristics of XPWR and provided a new way to use XPWR.

Abstract

Abstract: A simple, effective method has been demonstrated to immobilize Rhodamine B (RhB) probes on mesoporous silica (Au–HMS). The prepared chemosensor (Au–HMS–Probe) was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD), UV–vis spectrum and Fourier transform infrared spectroscopy (FT-IR). Further application of Au–HMS–Probe in sensing Hg2+ was confirmed by fluorescence titration experiment. Au–HMS–Probe afforded “turn-on” fluorescence enhancement and displayed high brightness in water, and it also showed excellent selectivity for Hg2+ over alkali (Na+, K+), alkaline earth (Mg2+, Ca2+) and other heavy metal ions (Ag+, Cd2+, Co2+, Pb2+, Ni2+, Cu2+, Fe2+). Importantly, Au–HMS–Probe could be regenerated by treatment with tetrapropylammonium hydroxide solution. [Copyright &y& Elsevier]
