this paper focuses on the effects of the addition of an ionic liquid, 1-allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([abim]tfsi), which has a high affinity for benzene, into the poly(vinyl chloride) (pvc) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. when aqueous solutions of 100～500 ppm benzene were permeated ...

The use of synthetic coagulants is not regarded as suitable due to health and economic considerations. Studies were carried out in laboratory scale on deionised water containing synthetic turbidity of kaolinite. Experiments were carried out in four turbidity ranges: 10, 50, 500, 1000 (NTU) and the pH range 5-8. The efficiency of moringa oleifera seed extract and polyaluminum chloride was examin...

The Badaksinga Drinking Water Processing Installation is an installation owned by Perumda Tirtawening Water, Bandung City, has 2 of these installations, the first which a design from Degremont - France, built around 1954 with capacity 1000 liters/second. second IWACO-Dutch flow rate 800 raw water for two installations comes Cisangkuy River and Cikapundung River. To purify water, PAC (Poly Alumi...

Several studies reported many neurodegenerative disorders and Alzheimer' disease induced by aluminum chloride on cerebral cortex of male rats. Coriander (Coriandrum sativum) is a plant among others which improve blood circulation to the head, impart mental concentration and memory capabilities. Coriander, both its leaves and its seeds are grown as spice group all over the world. The present inv...

Two coagulants, aluminum sulfate and ferric chloride, were tested to reduce natural organic matter (NOM) as a pretreatment prior to polyvinylidene fluoride (PVDF) microfiltration (MF) membranes for potable water treatment. The results showed that the two coagulants exhibited different treatment performance in NOM removal. Molecular weight (MW) distributions of NOM in the tested surface raw wate...

The possibility of using molten mixtures of 1,4-dimethyl-l,2,4-triazolium chloride (DMTC) and aluminum chloride (A1C13) as secondary battery electrolytes was studied, in some cases extended by the copresence of sodium chloride. DMTC-A1CI~ mixtures demonstrated high specific conductivity in a wide temperature range. The equimolar system is most conductive and has K values between 4.02 x 10 -~ an...

OBJECTIVE To evaluate the effects of different hemostatic agents upon the outcome of periapical surgery. DESIGN A retrospective study was made of patients subjected to periapical surgery between 2006-2009 with the ultrasound technique and using MTA as retrograde filler material. We included patients with a minimum follow-up of 12 months, divided into two groups according to the hemostatic age...

OBJECTIVE To find out the effect of wheat grass on aluminum induced Alzheimer's disease in Wistar rats. METHODS Memory impairment was induced by aluminum chloride (4.2 mg/kg, i.p.) for 28 d. Memory function was assessed by Morris water maze test. To study the activity of wheat grass (100 mg/kg, p.o.), Wistar rats were administered it for 28 d along with aluminum chloride. Biochemical paramete...

Water treatment using nano-materials can have a significant impact due to its surface properties. Coagulation techniques were studied by 3 mL/L of 0.5% different coagulants (polyacrylamide, poly aluminum chloride (PAC), ferric chloride, sulfate, and nanocellulose). Results indicated that the turbidity removal efficiency 91.6%, 93.04%, 95.2%, 95.4%, 99.4%, respectively. Treatment water samples c...
