Aluminum-based water treatment residuals (WTR) can adsorb water- and soil-borne P, As(V), As(III), and perchlorate, and may be able to adsorb excess environmental selenium. WTR, clay minerals, and amorphous aluminum hydroxide were shaken for 24 h in selenate or selenite solutions at pH values of 5-9, and then analyzed for selenium content. Selenate and selenite adsorption edges were unaffected ...

Background & Aims: The topical anesthetic effects of diphenhydramine combined with ingredients such as aluminum and magnesium hydroxide have been used for many years in modern medicine. Due to the limited durability of anesthetic mouthwashes due to saliva secretion and the spreading use of herbal and natural medicines in pharmacotherapy, this study was designed to formulate diphenhydramine in t...

haemorrhagic septicaemia (hs) vaccine which is prepared in razi institute is used in endemic areas ofiran. aluminum-hydroxide gel was used as adjuvant for preparing this vaccine. post-vaccinal shock reactionswere the main complaint after use of this vaccine. in a previous study, we could improve the vaccine byalum-precipitation pasteurella multocida cells and removing the liquid phase. in this ...

The methods commonly used for precipitating aluminum by 8-hydroxyquinoline from an acetic-acid solution, buffered with ammonium acetate, do not sufficiently define the conditions requisite for complete precipitation. The present article describes a method in which aluminum is precipitated as the oxyquinolate from a solution which has been partially neutralized with ammonium hydroxide, using bro...

chemical wastewater treatment is one of the attracting and common methods for wastewater treatment among the currently employed chemical unit processes. the use of coagulant-flocculant compound is one of the efficient methods for separating of paint and recovery of water. in this research, it was introduced and the effect of ph on removal of solid content from solution was studied experimentall...

The IgE production was compared in the presence and absence of aluminum hydroxide gel (alum). Without alum, the IgE production was induced within a suitable range of the antigen dosage; however, alum enhanced it. Alum did not affect the minimum requirement for the antigen dosage, indicating that alum may not take part in the efficiency of antigen presentation.

The goal of the present thesis was to study the possibilities of producing an aluminium hydroxide, which would easily dissolve in hydrochloric acid. Furthermore, the product should be easy to dewater. In the experiments, which were made batch-wise, a 50% sodium hydroxide was used to accomplish the precipitation. The precipitation of aluminium hydroxide is a dynamic process that depends on many ...

Ab initio, molecular orbital calculations for two different Hartree-Fock basis levels were performed on clusters in the system Al-O-H, and tested by comparing derived vibrational frequencies to the measured values for aluminum oxides and aluminum oxyhydroxide minerals. Models were chosen to reflect surface groups that may be present on aluminous minerals such as a-Al2O3 (corundum) and Al(OH)3 (...
