The first reaction product on chlorination is cyanogen chloride (CNCl), a highly toxic gas of limited solubility. The toxicity of CNCl may exceed that of equal concentrations of cyanide. 2,3,12 At an ,alkaline, pH, CNCl hydrolyzes to the cyanate ion (OCN −), which has only limited toxicity. There is no known natural reduction reaction that may convert OCN − to CN −. 13 On the other hand ...

A mesoporous silica prototype (MSP) was produced by attaching SiO2 colloid to urea ,formaldehyde, resin. Treatment of the MSP using different grafting methods yielded three different amino-functionalized mesoporous silica samples. The materials were characterized by scanning electron microscopy, energy-dispersive spectroscopy, transmission electron microscopy, X-ray photoelectron spectroscopy ...

Practically every phase of water supply and ,wastewater, treatment are pH dependent. At a given temperature the intensity of the ,acidic, or basic character of a solution is indicated by hydrogen ion activity and referred to as pH. On a scale of 1 – 14, pH 1 is considered strongly ,acidic, and pH14 highly ,alkaline, (or ‘base’).

The solubility and rate of solution of ,paraformaldehyde, in water are greatly influenced by pH and temperature. Both ,acidic, and ,alkaline, pHs and higher temperatures accelerate the rate of solution. Once dissolved, the ,paraformaldehyde, solution behaves like the methanol-free ,formaldehyde, solution of the same concentration.
