Prevention of acute ammonia toxicity in beluga, Huso huso, using natural zeolite
This study was accomplished to examine the efficiency of natural zeolite in preventing acute toxicity of total ammonia to Huso huso. The study was performed using Water Static Method in 96 hours. Fish averaged 46 ? 5 g in weight and 22 ? 4 cm in total length were exposed to four different concentrations (15, 30, 50, 75 mgL-1) of ammonia and a group was considered as control. Under stable condit...
متن کاملmodification of drastic model to map groundwater vulnerability to pollution using nitrate measurements in agricultural areas
drastic model has been used to map groundwater vulnerability to pollution in many areas. since this method is used in different places without any changes, it cannot consider the effects of pollution type and characteristics. therefore, the method needs to be calibrated and corrected for a specific aquifer and pollution. in the present research, the rates of drastic parameters have been correct...
متن کاملThe Effect of Modification and Initial Concentration on Ammonia Removal from Leachate by Zeolite
The purpose of this study is to investigate the capacity of natural Turkish zeolite for NH4-N removal from landfill leachate. The effects of modification and initial concentration on the removal of NH4-N from leachate were also investigated. The kinetics of adsorption of NH4-N has been discussed using three kinetic models, i.e., the pseudo-second order model, the Elovich equation, the intrapart...
متن کاملUranium removal from groundwater by natural clinoptilolite zeolite: effects of pH and initial feed concentration.
Adsorption of uranium (VI) on a natural clinoptilolite zeolite from Sweetwater County, Wyoming was investigated. Batch experiments were conducted to study the effects of pH and initial feed concentrations on uranium removal efficiency. It was found that the clinoptilolite can neutralize both acidic and low basic water solutions through its alkalinity and ion-exchange reactions with U within the...
متن کاملLead pollution removal from water using a natural zeolite
Lead (II) ion adsorption capacity of clinoptilolite from artificial polluted tap water was investigate in this study. For the experimental studies, Clinoptilolite mineral which is 25-140 mesh size was used by activating with HCl, and lead ion removal efficiencies were examined. Experiments were studied under laboratory batch conditions were run at different pH values, temperatures. The highest ...
