The water rinse represents a major departure-from the conventional single dip in sodium bisulfite solution.
Six chemicals can be used: sulfur dioxide, sodium sulfite, sodium bisulfite, potassium bisulfite, sodium metabisulfite and potassium metabisulfite.
Those are some of the things that will affect people's lives," said Nairobi Health CEC Mohammed Dagane.Nairobi County's deputy director, public health, Mr Kenneth Maina, said sodium bisulfite is a permissible food preservative but the limit must not be exceeded and must be indicated on the packaging for the customer to decide whether to buy meat with preservatives or without.
Tenders are invited for supply of the liquid sodium bisulfite shall contain no insoluble matter by weight; and meet the ansi/nsf standard 60.
Aliquots of 10 mM hydroquinone and 3 M sodium bisulfite (pH 5.0) were added and the solution was incubated at 50[degrees]C for 16 hr.
The DNA methylation status of the promoters of interest can be detected directly via such methods as methylation-sensitive restriction analysis (15), but the most commonly used techniques rely on chemically treating target DNA with sodium bisulfite. Under suitable conditions, this chemical reagent converts unmethylated DNA cytosines to uracils but leaves unchanged methylated cytosines, such as those within CpG dinucleotides (16, 17).
First, read all ingredient labels for any of six sulfites: sulfur dioxide, sodium sulfite, sodium bisulfite, potassium bisulfite, sodium metabisulfite, potassium metabisulfite; sometimes they are listed simply as "sulfiting agent." Sulfites are required to be listed if they leave any detectable residue.
The clarified water flows over the effluent weirs and discharges to the excess flow chlorine contact basin, where the flow is disinfected by sodium hypochlorite and dechlorinated with sodium bisulfite. Fully treated excess flow effluent is then blended with the plant's main effluent and conveyed by gravity through an outfall pipeline for discharge into the Kansas River.
