Simultaneous removal of Cr(VI) and Amido black 10B (AB10B) from aqueous solutions using quaternized chitosan coated bentonite

Natural and synthetic aluminosilicate minerals, in particular zeolites, are considered to be very useful in remediation processes, such as purification of waters polluted with heavy metals. That is due to their unique and outstanding physico-chemical properties, rendering them highly efficient, low-cost, and environmentally friendly sorbents of various environmental pollutants. The aim of this study was to examine the sorption capacity of four selected zeolites: A natural zeolite and three synthetic zeolites (3A, 10A, and 13X), towards zinc and cadmium present in multicomponent aqueous solutions, in relation to identified sorption mechanisms. It was stated that synthetic zeolites 3A and 10A were the most efficient in simultaneous removal of zinc and cadmium from aqueous solutions. Additionally, zeolite 10A was demonstrated to be the mineral best coping with prolonged pollution of water with those elements. The mechanism of sorption identified for tested minerals was physisorption.

Amido Black

Interphase nucleoli of Ehrlich ascites tumor cells were stained with amido black 10B to the exclusion of all other regions of interphase and mitotic cells. Proteins of the ascites fluid also remained unstained. Selectivity of the dye for nucleolar protein, established by blocking and extraction methods, is metal-mediated and involves amino groups predominantly. The conditions leading to selectivity are narrowly circumscribed in Ehrlich ascites tumor cells and, thus far, have not yielded equally satisfactory results with nontumor material to warrant general applicability of the method. A tentative explanation of the phenomenon is offered on the basis of numerous control experiments involving freezing-drying, variations in composition and application of reagents and other pertinent cytochemical procedures. The findings suggest that nucleolar proteins possess certain unique properties which are lost on altered to the extent that they are insensitive to the amido black 10B method once the proteins are released from the interphase nucleolus.
