Background and Objective: Main sources of 4-chlorophenol wastewater are petroleum industry, coal, paper and resin production. The aim of this study was to compare the performance of raw and cationic surfactant modified nanoclay in removal of 4-chlorophenol from aqueous solutions. Materials and Methods: The influence of contact time, initial pH of solution, adsorbent dosage and 4-chlorophenol c...

in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
sawdust of the most inexpensive and abundant most engrossing read and the ability to absorb heavy metals from water and wastewater types. on the other hand increased metal hexavalent chromium (cr6 +) in drinking water cause toxicity, and complications from it can be. so the purpose of this research, effects of the dosage absorbent sawduste, equilibrium time, the efficiency of absorption and cal...
