F. Zadjanali Choubari; M. Navabian; M. Vazifehdust; M. Esmaeili Varaki

Volume 27, Issue 6 , January and February 2014, , Pages 1166-1175

https://doi.org/10.22067/jsw.v0i0.33124

Abstract
  Phosphorus is one of the main pollutants of agricultural surface drainage; that over standard doze of it cause eutrophication in surface water resource. This study investigates evaluation the ability of Semnan's zeolite, that modified by hexadecyltrimethylammonium, to removal phosphorus under flow conditions ...  Read More
