Detergents; 

maximum phosphate sorption amount and reaction rate were achieved in the zirconium mesostructure synthesized with the surfactant of dodecyltrimethylammonium bromide(1232,;)

The synthesis of gold nanoparticles has been carried out in aqueous phase in the presence of both ionic surfactants (i.e., sodium dodecylsulfate (SDS) and (DTAB)) and poly(amidoamine) dendrimers (PAMAM)
