Spectroscopic Study of Alizarin and Alizarin Red Adsorbed on Anodic Aluminum Oxide Films

Electrocoagulation removal of anthraquinone dye Alizarin Red S from aqueous solution using aluminum electrodes:

Electrocoagulation (EC) was used for the removal of anthraquinone dye, Alizarin Red S (ARS) from aqueous solution. The process was carried out in a batch electrochemical cell with Al electrodes in a monopolar connection. The effects of some important parameters such as current density, pH, temperature and initial dye concentration, on the process were investigated. Equilibrium was attained afte...

Spectrophotometric determination of ceterizine hydrochloride with Alizarin Red S.

A simple, rapid and sensitive spectrophotometric method has been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and its pharmaceutical preparations. This method is based on the ion-pair complex reaction between CTZH and Alizarin Red S in Clarks-Lubs buffer. The chromogen being extractable with chloroform, could be measured quantitatively at 440 nm. All variables were st...

Anodic aluminum oxide microchannel plates

A new material for microchannel plates (MCP) is proposed — anodic aluminum oxide. Microchannel plates made of this material may be much cheaper than with conventional lead glass MCP. Also a significantly smaller channel diameter (up to 70 nm) is easily achievable, which means better spatial resolution and the possibility to operate in strong magnetic fields. Methods and means are developed for ...

Skeletal examination by alizarin staining.

A skeletal examination of fetuses is required in regulatory embryo-fetal development studies. This chapter describes a method of skeletal examination using alizarin staining. All fetuses are removed from the mother by caesarean section before birth. The fetuses are first examined externally. For larger species (rabbit and minipig), an internal examination can be performed on the fresh soft tiss...
