Fixed-bed adsorption of copper from aqueous media using chitosan-coated bentonite, chitosan-coated sand, and chitosan-coated kaolinite.

Fixed-bed studies were performed to evaluate the removal efficiency of copper (Cu(II)) from aqueous solution using chitosan-coated bentonite (CCB), chitosan-coated sand (CCS), and chitosan-coated kaolinite (CCK). The thermal and morphological properties of CCB, CCK, and CCS were characterized using thermogravimetric analysis, Fourier transform infrared spectroscopy, and the Brunauer-Emmett-Teller method. Dynamic experiments were carried out to investigate the effect of solution pH (3.

Social support and caregiving circumstances as predictors of caregiver burden in Taiwan.

Previous research has failed to consider the importance of caregiving circumstances and their impact on social support and caregiver burden. Hence, this study aimed to investigate the association between perceived and received social support and caregiver burden. This cross-sectional study was carried out on 301 family caregivers.

CWAO of phenol using CeO2/gamma-Al2O3 with promoter--effectiveness of promoter addition and catalyst regeneration.

The effect of promoter addition on activity of CeO(2)/gamma-Al(2)O(3) was assessed via the CWAO of phenol. Adding Cu as the promoter rendered the most effective performance, followed by Mn, although the performance of Mn-promoted catalyst was inferior to CeO(2)/gamma-Al(2)O(3). Mineralization of phenol was effectively implemented at 160 degrees C using Cu-promoted catalyst (Ce15Cu5).

The health status of family caregivers in Taiwan: an analysis of gender differences.

Background: Many studies have assessed the impact of caregivers' work activities on the caregiver. There is growing concern about the ever-increasing problems, both physical and physiological, faced by health care workers who provide care for the ill and incapacitated.

Aim: The aim of the study was to examine what, if any, differences exist between male and female caregivers.

An assessment of the suitable operating conditions for the CeO2/gamma-Al2O3 catalyzed wet air oxidation of phenol.

It has been shown that the CeO2/gamma-Al2O3 catalyst is a feasible alternative to CeO2 for the catalytic wet air oxidation (CWAO) of phenol because it remains an effective catalyst and yet is cheaper to prepare. In this study, we found that the optimal cerium content in the CeO2/gamma-Al2O3 catalyst was 20 wt.%, regardless of catalyst loading.

Wet air oxidation of a reactive dye solution using CoAlPO(4)-5 and CeO(2) catalysts.

Wet air oxidation of a prepared reactive dye solution was performed to assess the efficacy of CoAlPO(4)-5 and CeO(2) as catalysts in the reaction. Via adsorption and oxidation of dye, CoAlPO(4)-5 effectively decreased American Dye Manufacturers Institute and chemical oxygen demand (COD) values in the dye solution. At a reaction temperature of 135 degrees C and an applied pressure of 1.
