With the development of industry and agriculture, increasingly serious problems environmental pollution water quality deterioration that affect human health need to be solved. Materials containing both Fe Mn, two most abundant metal elements, have been widely used for wastewater decontamination since they are nontoxic, low-cost, easy prepare, highly efficient. This review systematically summari...
BACKGROUND Occupational contact dermatitis among hairdressers is frequent, owing to daily exposure to irritants and allergens. OBJECTIVES To identify sensitization to the most common allergens associated with the occupation of hairdressing. METHODS Patch test results of 399 hairdressers and 1995 matched controls with contact dermatitis, registered by the Danish Contact Dermatitis Group betw...
As an abundant potentially dangerous waste, red mud (RM) requires a straightforward method of resource management. In this paper, RM catalyst loaded with cobalt (Co-RM) was prepared by the coprecipitation for efficient activation persulfate (PS). Its degradation performance and mechanism ofloxacin (OFL) were investigated. The characterization results scanning electron microscopy, X-ray diffract...
oxygen delignified kraft pulp from eucalyptus (e. urophylla × e. grandis) was catalytically pretreated in aerobic condition using ammonium persulfate in present of catalists like cupric acetate and/or cobalt acetate in acetic acid-water solution, i. e. s2o82--cu2+, s2o82--co2+ and s2o82--(cu2++co2+). final bleached pulp after pretreatment with the three catalytic systems showed higher delignifi...
INTRODUCTION Since persulfate salts are an important cause of occupational asthma (OA), we aimed to study the persistence of respiratory symptoms after a single exposure to ammonium persulfate (AP) in AP-sensitized mice. MATERIAL AND METHODS BALB/c mice received dermal applications of AP or dimethylsulfoxide (DMSO) on days 1 and 8. On day 15, they received a single nasal instillation of AP or...
To improve the photo-catalytic degradation of salicylic acid, we reported the fabrication of ordered TiO2 nanotube arrays by a simple and effective two-step anodization method and then these TiO2 nanotubes were treated in a methanol solution under UV light irradiation. The TiO2 nanotubes prepared in the two-step anodization process showed better photo-catalytic activity than those prepared in o...
