Biosorption is becoming a promising alternative to replace or supplement the present dye removal processes from dye wastewaters. Based on the results of batch studies on biosorption of the dyes on powdered fungal biomass, Aspergillus niger, an immobilised fungal biomass was used in column studies for removal of four dyes, Acid Blue 29, Basic Blue 9, Congo Red and Disperse Red 1 from aqueous sol...

Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

in this paper, leaching of lead and cadmium was investigated from porcelain over glaze designs between different colors.  also the effect of microwave heating was considered on leaching of lead and cadmium.  dishes were selected with a decor with the dominant color of gray, red, yellow, blue, and dark blue. amounts of cadmium and lead which leached from the container by acetic acid and orange j...

Selective troponin I (TnI) modification has been demonstrated to be in part responsible for the contractile dysfunction observed with myocardial ischemia/reperfusion injury. We have isolated and characterized modified TnI products in isolated rat hearts after 0, 15, or 60 minutes of ischemia followed by 45 minutes of reperfusion using affinity chromatography with cardiac troponin C (TnC) and an...

Orcein-alcian blue staining, a new method for the simultaneous demonstration of sulphated and sialomucins in gastrointestinal epithelium was compared with the standard high iron diamine-alcian blue technique. Sections were oxidised with potassium permanganate and decolourised in oxalic acid. They were stained with orcein for four hours, differentiated for a few seconds in acid alcohol, and then...

In this work, adsorption kinetics were investigated in order to remove the acid blue 62 off the aqueous solutions using mesoporous silicate SBA-15 loaded with tannic acid (tannin-SBA-15). Nitrogen adsorption and desorption test (BET), X-ray diffraction (XRD) and Fourier transform infra-red spectroscopy (FT-IR) analysis characterize synthesized composite. The impacts of some parameters such as P...
