The desilication effects of aluminium sulphate and sodium aluminate on kraft bamboo pulp during the cooking process were investigated in this study. Furthermore, the residual aluminium ion concentration in the resulting black liquor was measured by inductively coupled plasma atomic emission spectrometry (ICP-AES) to evaluate the scaling properties of black liquor during the evaporation process....

M. Gonella, MD, Servizio di Nefrologia e Dialisi, Ospedale S. Spirito, I-15033 Casale Monferrato (Italy) Dear Sir, Despite early suggestions about aluminum (Al) absoφtion and toxicity in renal failure [ 1 ], Al hydroxide was widely used as a phosphate binder until a few years ago. In the late 70s, Al metabolism was more deeply investigated and its deposition in various tissues was found to be c...

Strongly increased KCl prices force to modify the current salts mixture in the currently used salt treatment processes for aluminium recycling. This study presents lab-scale results about the influence on metal yield varying both the NaCl:KCl ratio from 70% to 100% NaCl and the CaF2content from 0% to 3%. The metal yields showed no significant difference at higher NaCl:KCl ratios and as commonly...

IT has been generally assumed that the anticoagulant action of heparin is due to direct combination with prothrombin, thrombin, or kinase. The chief experimental facts on this point have been confirmed by Mustard & Jaques [1937] and may be summarized as follows. When citrated plasma and thrombin are used to test the action of heparin, the heparin acts as an antithrombin [Howell, 1925]. When kin...

Complex formation processes of sericin compounds with Ni 2+ , Cu Zn Co salts were studied. The possibility maximum extraction was determined when wastewater is purified by the proposed method, and developed purification method recommended for amino acid wastewater. By using coagulants Al2(SO4)3•18H2O FeCl3•6H2O flocculant PAA together sorbent, concentration in 0.75 mg/l, 0.5 amount kaolin bento...

Chemical treatment of animal manure with Al, Fe, and Ca salts appears capable of concentrating P in a smaller volume, thereby providing increased manure management options. However, little information is available on the fate of nutrients in soils receiving chemically treated manure. An incubation study (1 d to 2 yr) was conducted with three soils (Soils I, II, and III with 12, 66, and 94 mg kg...
