Adsorption paper chromatography of inorganic substances

Journal of Chromatography A, 1961
Summary Some of the compounds of Sn(II) with platinum metals may be separated by adsorption chromatography on paper. Their behaviour in SnCl 2 -HCl and SnBr 2 HBr was noted.

Adsorption of unknown substances for aqueous solutions

Chemical Engineering Science, 1991
Abstract The procedure proposed by Jayaraj and Tien for characterizing the adsorption affinity of solutions with unknown compositions was modified by assuming that the solute concentrations may be described by the binomial distribution function. This new method yields results comparable to those of the original Jayaraj—Tien procedure although it ...

Substance removal with adsorption

Filtration + Separation, 2018
The manufacture of pharmaceuticals frequently results in effluent being released when the production plants are cleaned. However, they can be removed from the wastewater by adsorptive treatment processes. SARATECH® adsorbents from Blücher are especially well suited for this task.

Atomization of Nanopowders for Adsorption of Toxic Substances

Journal of Engineering Physics and Thermophysics, 2015
An experimental investigation of the dispersity and the specific surface of the particles of a pseudoboehmite nanopowder atomized by different methods for the purpose of formation of an aerosol has been carried out. It is shown that, as a result of the atomization of this power, the specific surface of its particles decreases and that this decrease is ...

Adsorption of Pesticide by Humic Substances. A Review

Environmental Letters, 1972
Abstract The literature pertaining to adsorption of pesticide by humic substances has been reviewed. Results of various investigations and mechanisms for pesticide adsorption are discussed. The effects of such factors as temperature and pH, and the techniques for the study of pesticide adsorption by humic substances are outlined.

ADSORPTION OF CHLORDIMEFORM BY HUMIC SUBSTANCES FROM DIFFERENT SOILS

Soil Science, 1990
We studied the interaction of the cationic pesticide chlordimeform with humic and fulvic acids from different soils. The mechanism of chlordimeform adsorption is essentially a cation exchange reaction. Adsorption is influenced by the origin of the humic substances because of the different content in functional groups.

Effect of adsorption of organic substances on theelectroreduction of cations

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1970
Summary The exchange current density values for the zinc amalgam electrode, Zn(Hg)/Zn 2+ in 5· 10 −2 N Na 2 SO 4 in both the presence and absence of surface active organic substances, n-valeric acid, diethyl ketone and n-amyl alcohol, were determined by the galvanostatic transient method.

Removing Humic Substances by Chemical Treatment and Adsorption

Journal AWWA, 1985
Alum coagulation and lime softening exhibited variable effectiveness for removing the total organic carbon (TOC) associated with humic substances in water supplies. Pretreatment with alum or lime also affected the subsequent adsorption of TOC by granular activated carbon, with alum coagulation generally improving overall adsorbability.

Removal of Humic Substances and Their Metal Complexes by Adsorption

Environmental Engineering Science, 2004
The adsorption of organic polyelectrolytes (humic and fulvic acids) by bone char was characterized. The bone char was found to be a useful adsorbent for humic substances compared with an activated carbon. The present method was also successfully applied to the removal of metal-humic material complexes.
