Agarose molecular weight marker. advantage: much less shadow on EtBr pictures unlike xylene cyanol and bromophenol blue molecular weight 404 g/mol

Cresol Red Dye Removal Using Recycled Waste Tire Rubber

Dyes represent one of the persistent pollutants, which are difficult to remove from wastewater by the conventional treatment methods. Low cost adsorbents prepared from tire rubber waste were used to remove cresol red dye from liquid solution. In order to save energy no agitation or activation were made on the adsorption process. This will naturally slow down the process, but time was compared .

Interactions of Cationic, Anionic and Nonionic Surfactants .

Abstract The interaction of cresol red (CR) with cetylpyridinium bromide (CPB), sodium dodecyl sulphate (SDS), and Triton X-100 (TX-100) was studied in aqueous solutions employing conductometric, tensiometric, and spectroscopic methods. Various micellar and interfacial parameters were calculated in absence and in presence of CR. The interactions suggest the formation of a CR-CPB adduct, an .
