A common step in most of water treatment plants is the chemical coagulation. The chemical coagulation is the process of destabilizing the colloidal particles suspended in raw water by the addition of coagulants. Generally, the determination of the quantity of coagulant to be added to water is made manually by jar tests. However, the manual control has slow response to changes of raw water and i...

a new poly(vinylchloride) membrane sensor for cr3+ ions based on di (benzylamino)glyoxime asan ionophore was prepared. the electrode has a linear dynamic range 1×10-6-1×10-1 mol l-1,with anernstian slope of 20.3 ± 0.5 mv per decade and a detection limit of 2×10-7. it has a fast responsetime of

methoxy poly(ethylene glycol) (mpeg) with molecular mass of 5 kda activated with succinimidyl carbonate and cyanuric chloride, separately was covalently attached to human red blood cells (rbcs). inhibition of agglutination by blood-type specific antisera (anti-d) was employed to evaluate the effect of the polymer coating. the remaining single cells after incubation with anti-d sera were counted...

A polymer gel electrolyte using AlCl3 complexed acrylamide as a functional monomer and acidic ionic liquid based on a mixture of 1-ethyl-3-methylimidazolium chloride (EMImCl) and AlCl3 (EMImCl-AlCl3, 1-1.5, in molar ratio) as a plasticizer has been successfully prepared for the first time via free radical polymerization. Aluminum deposition is successfully achieved using a polymer gel electroly...

Aluminum chloride hexahydrate concentration-dependently inhibits perspiration and is highly effective in palmar and axillary hyperhidrosis. The main effect is in the sealing of the sweat glands, the precipitation of aluminum-mucopolysaccharide-complexes and the damage to the epithelial cells in the excretory ducts of the eccrine sweat glands result in sealing of these ducts. Other aluminum salt...

Problem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity wa...

An aluminum metal, both native and with a very thin oxide film, was investigated as an anode for aluminum-ion batteries. Investigations were carried out in an acidic ionic liquid electrolyte, composed of AlCl3 in 1-ethyl-3-methylimidazolium chloride ([EMIm]Cl), with β-MnO2/C as a cathode. The battery based on Al metal with a very thin oxide film showed high capacity and stable surface corrosion.

Ammonia (NH3) losses from swine manure contribute to odor problems, decrease animal productivity, and increase the risk of acid rain deposition. This study was conducted to determine whether aluminum chloride (AlCl3) or dietary manipulation with phytase could decrease relative NH3 losses from swine manure. Twenty-four pens of nursery pigs were used in two trials, and the pigs were fed normal or...
