the reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (mb+) incorporated in nanomordenite and na-mor zeolites. the rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than na-mordenite (na-mor) zeolite.because nanomordenite zeolite with high si...

abstract purpose: skeletal staining is a way to study the effect of many chemical or herbal substances on development of bones and cartilages in order to record the level of probable deformity.this article aimed to present a modified protocol to make all skeletal studies on laboratory animals possible. materials and methods: the important notes about skeletal staining were fixing by ethanol and...

the present work reports a kinetic spectrophotometric method for the determination of traceamounts of sulphite that is based on inhibitory effect of sulphite on the oxidation of methyleneblue (mb) in acidic media. the reaction is followed spectrophotometrically by monitoring thedecrease in absorbance of mb at 664 nm with a fixed time of 0.5-4.5 minutes. it was found thatsulphite exert a strong ...
