| Abstract: | The viscosity of the solution of humic acid,fulvic acid and hvmatomelanic acid extracted from some soils was studied.Results obtained indicaed that they are all nonspherical colloid.The intrinsic viscosity of them in 0.1N NaCl is of following decending order:fulvic acid>humic>hymatomelanic acid. |
