Synthetic colors are generally utilized in the industrial section for the chemical consistency and ease of synthesis. Micropollutants in water sources propose an actual hazard to the natural ecosystem and the health of humans (Kim and Zoh, 2016). The traditional procedures have been limited approaches for dealing by sewage pollutants. Furthermore, Advanced Oxidation Processes, according to the hydroxyls radicals' generation, have been discovered and indicated to be influential procedures for removing the poisonous chemical mixes. In this study, we have investigated Fenton and Photo-Fenton procedures' performance on the Blue levafix color degradation, as a substitution technique for the textile industry swage treatment. The irradiation intensity impact, initial color concentration, initial PH, iron concentration, nitrate, and organic material have been investigated. The whole irradiation investigations have been gained at 365 nm utilizing high-pressure mercury lamp (Philips HPW, 15 W). Levafix Blue color discoloration kinetics has been monitored by UV-Vis spectrophotometer analysis in the highest adsorbsion wavelength (613 nm). So, under an acidic medium, it has been regarded that both procedures, Fenton and Photo-Fenton, could remove around 99 percent of contaminants. Nevertheless, the iron concentration growth causes the response prohibition.

Describing spatial deviations in pasturage ecosystem water-utilization performance (ewup) would help our knowledge of how pasturage ecosystems' water responds to weather change.

Describing spatial deviations in pasturage ecosystem water-utilization performance (ewup) would help our knowledge of how pasturage ecosystems' water responds to weather change. Nevertheless, complete knowledge of the spatial deviations of ewup in Inner Mongolia's temperate pasturage is yet to be get. We have analyzed the spatial patterns of ANPP and ewup along with a rainfall rise in the pasturage. The ANPP advanced exponentially with rising mean annual evapotranspiration (MAE). The ewup grew linearly by growing mean annual precipitation (MAP).

Nowadays, the interpolation methods have become an important technology on the groundwater research. Many geographic information system software based on different interpolator tools have been developed and used widely such as ArcGIS, MapInfo and ArcView. This study was conducted to evaluate interpolation tools for the prediction of HCO3, Cl, SO4, Ca and Na distribution in groundwater of northern regions of Khuzestan province. Inverse distance weighted, kriging, radial basis functions, local and global polynomial interpolation were five interpolation methods that used for this subject. 98 deep wells was selected and chemical analysis data was collected in summer 2008. Predicted values of contaminants were compared to observed data by RMSE, MAE (Mean Absolute Error) and MSDR (Mean Squared Standardized Deviation Ratio) indexes to select the optimum interpolator technique. The results show that the kriging method has the highest interpolation accuracy among five interpolation methods for mapping Ca, SO4 and HCO3 by RMSE equal to 0.56, 0.9 and 0.6 respectively. Also, RBF and IDW Methods have acceptable estimations for Cl and Na ions.
