Adsorption of Some Alkaloids by Different Clays*

Adsorption Studies on Clays I**Department of Pharmacy, Philadelphia College of Pharmacy and Science, Philadelphia, Pa.

“…PRELIMINARY STUDY in our laboratory (1) A revealed that the clays attapulgite and halloysite are superior to kaolin as adsorbents for strychnine, quinine, and atropine. It occurred to us that, since these clays were superior to kaolin in adsorbing alkaloids, they may also be superior in adsorbing toxins and bacteria.…”

Predicting the Effect of Nonionic Surfactants of Interfacial Tensions

“…(See Appendix.) The validity of using concentration instead of pressure, as given in the original Langmuir equation, has been demonstrated by Barr et al (6).…”

Adsorption and separation of proteins by a smectitic clay mineral

“…Smectitic clay minerals are suitable for adsorption of proteins and immobilization of enzymes [3,[12][13][14]. Also other biologically active molecules such as alkaloids [15][16][17], nucleic acids [18,19], different organo phosphorous pesticides [20][21][22] and nitro aromatic compounds [23,24] as well as viruses [25][26][27] can be adsorbed. Moreover (poly)saccharides can be adsorbed or intercalated in dependence of their charge status [28,29].…”
