studies on sorption of congo red from aqueous solution onto soil
the aim of this study was to investigate the congo red sorption on soil from the region of iasi (ne of romania). the effects of contact time, temperature, sorbent dose and initial dye concentration on soi sorption were investigated. the results show that the amount adsorbed of congo red on soil increase with increasing dye concentration, temperature and contact time. the experimental data were ...

متن کاملThe congo red stain revisited.
The Congo red stain has undergone several modifications since it was first used by Bennhold in 1922 in order to increase the specificity for staining amyloid. Most of the laboratories in the United States use the method of Puchtler which uses alkaline Congo red solution. Some of the variables associated with the procedure were investigated by us. Our results showed the following: (1) amyloid sh...
متن کاملReevaluation of Congo red test as reticuloendothelial system function test using tritiated Congo red autoradiography.

Med., 1973, 109 (3), 251-259 Tritiated Congo red was prepared by the gas exposure method. Analytical results obtained by thin layer chromatography and spectrophotometry indicated that the radioactive Congo red thus prepared h...
متن کاملIntra-cutaneous Congo red in rheumatoid arthritis.
It has been claimed that, in patients with amyloidosis, the presence of amyloid material in the skin may be demonstrated by the intracutaneous injection of Congo red (Philpott and Freshman, 1936; Nomland, 1936). In the presence of amyloidosis, the area of staining is said to be more intense and to persist for a longer time than in normal skin. Recently this technique has been employed by Laine,...
