introduction industrialization and urbanization of societies have caused many environmental problems. therefore, environmental protection has recently become highly important. water resources are particularly of high risk of pollution from industrial waste disposal to river, surface, and ground water, and also from discharge of water to municipal waste water collection systems. these effluents ...

salicylic acid is an important organic acid in plants rhizosphere soil exuded in the phosphorus (p) deficiency condition. to study the sorption behavior of p in the presence of salicylic acid, a batch experiment was conducted with different concentrations of salicylic acid (0, 2, 5 and 10mm) and p (0- 45 mg p/l) in a calcareous soil. the results showed that application salicylic acid decreased ...

Nonylphenol (NP) and bisphenol A (BPA) are two typical endocrine disrupter chemicals (EDCs) in reclaimed water. In this study, the adsorptions of NP, a branched NP (NP7) BPA on water-irrigated soils were studied by isothermal experiments, different environmental factors their investigated. The results showed that NP7 conformed to Linear model, adsorption Freundlich model. decreased with increas...

Sediments represent the major sink of antibiotics in aquatic systems. However, few studies have proposed effective models that can predict adsorption capacity sediments through their physicochemical parameters. Here, 49 sediment samples were collected from different locations Yangtze Estuary and its adjacent coastal areas. The characterized, behavior towards tetracycline (TC) was investigated. ...

Spongy graphene is a newly developed adsorbent of high performance for water treatment. Proper functionalization is an efficient approach to improve the adsorption capacity of graphene adsorbents. In this study, we prepared graphene oxide (GO), functionalized it with carboxyl groups to produce carboxylated GO (GO-COOH) dispersion, and lyophilized the GO-COOH dispersion to obtain the GO-COOH spo...
