“…Most studies have been carried out on the combined toxicity between Zn and other heavy metals [20,21,22]. There are also few studies that focus on the joint toxicity of Zn and organic chemicals [23,24]. Liu et al [23] investigated the joint toxicity of perfluorooctane sulfonate (PFOS) and zinc and the results show that the combined effects of the PFOS and Zn binary mixture to Limnodrilus hoffmeisteri were mostly simple addition.…”

The single toxicity (IC50) of zinc (Zn) and 11 nitro-substituted benzenes to Photobacterium phosphoreum were determined, respectively. On basis of single toxicity, the joint toxicity of binary mixtures of Zn and 11 nitro-substituted benzenes at different Zn concentrations of 0.2 IC50, 0.5 IC50, and 0.8 IC50 were measured. The joint toxicity was evaluated by toxic unit (TU) and additive index (AI) methods. The results indicated that the joint toxicity was not only depending on the Zn concentrations but also on the substituted groups of nitro-substituted benzenes. The quantitative structure-activity relation (QSAR) equations were developed and the results showed that the toxicity of nitro-substituted benzenes has different joint effect at the different Zn concentrations. At the Zn concentration of 0.2 IC50, the binary joint effects were mainly antagonism and the joint toxicity was negatively related to descriptors called VE2_B(p) and TIC3. At the Zn concentration of 0.5 IC50 and 0.8 IC50, the binary joint effects were mainly antagonism and simple addition, and the joint toxicity was related to the same descriptor Eig06_ AEA(dm). It indicated that the joint toxic actions were similar when combined at the medium and high concentrations of Zn.

BACKGROUND: Photocatalytic degradation of organic compounds, including nitrophenol, is one of the most popular approaches to pollution control and disposal. Graphene-based nanocomposites have attracted considerable attention in photocatalytic research owing to their excellent electrical, thermal and mechanical properties. In this work, TiO 2 material was modified with graphene by a hydrothermal method, the photocatalytic performance of the prepared catalyst was evaluated by degradation of 4-nitrophenol, which is a highly toxic, stable and carcinogenic organic pollutant. RESULTS:The characterization results showed that the low amount of graphene disperses well over TiO 2 and it does not influence the crystal phase, but makes the specific surface area of graphene/TiO 2 greater than that of TiO 2 . Compared with TiO 2 , graphene/TiO 2 exhibits enhanced photocatalytic activity for the degradation of 4-nitrophenol under simulated solar irradiation. CONCLUSION:The enhanced activity of photo-degradation could be attributed to the involved graphene being beneficial to charge transportation and separation of photogenerated charge carriers, and providing more surface active sites for degradation reaction of the target pollutant. The present result highlights the important application of graphene as a novel carbon material in treating highly toxic pollutant through photocatalysis technology.

“…Metal ions in industrial effluents are of great concern, which are harmful to the environment and living systems due to their persistent nature and toxicity [1]. As the second most abundant transition metal in the human body, zinc (Zn 21 ) plays important roles in many biological processes, such as apoptosis, gene expression, metalloenzymes regulation and neural signal transmission [2].…”

A kind of low‐cost silicon‐substituted carbonate hydroxyapatite (Si‐CHAP) powder was successfully fabricated by using eggshell powder, H3PO4, Ca(OH)2, Na2SiO3, and Na2CO3 under sonochemistry coprecipitation condition. Si‐CHAP could serve as an ideal adsorbent to remove zinc ion (Zn2+) from aqueous solution. Under the optimized conditions, the removal efficiency of Zn2+ in solution by Si‐CHAP could reach to 96.2%. The adsorption mechanism was investigated by X‐ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Notably, the adsorption process followed the Langmuir isotherm and pseudo‐second‐order model, and the saturation adsorption capacities were calculated to be 102.0, 103.1, and 105.3 mg g−1 at 293, 303, and 313 K, respectively. Thermodynamic studies indicated that the adsorption of Zn2+ by Si‐CHAP is endothermic. Mechanism studies revealed that the dominate mechanism was chemical adsorption. These results showed that Si‐CHAP is an effective adsorbent for the removal of Zn2+ from aqueous solution, and thus providing a good method to treat Zn2+ in the waste water. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1901–1907, 2018
