Introduction: Since the existing methods to remove the hazardous material are associated with problems, recently, the tendency is to use Biosorption methods by Low-cost adsorbents: this was investigated in our project. This study was conducted to investigate the adsorption of lead and zinc from aqueous solution by using powdered excess sludge (biosolid) from sludge drying beds of municipal wast...

The accretionary events began in the Cretaceous and have continued until recent times. The Herat or Hari Rod fault, which runs E-W acr...
Abstract Zinc ion dissolved in water is attempted to be removed by generating the oxides of zinc using oxygen gas dielectric barrier discharge (DBD) plasma system. The removal rate oxides’ production (ZnO and Zn(OH) 2 ) are measured at different treatment periods penetration water. deposit increases initially then decreases with period. maximum (29%) from achieved period 10 min, where pH lower ...
