WebJan 1, 1982 · A variety of organic substances in a water supply can prevent optimum operation of a deionizer. The most frequent problems are caused by humates and fulvates. Anion-exchange resins are more susceptible to these adverse effects than cation exchangers and mixed beds more than multiple beds. The symptoms of “organic fouling” … WebIf the substance has a strong tendency to lose electrons, then it is said to be a strong reducing agent (since it will reduce the other substances by donating electrons). Atoms with relatively large atomic radii tend to be better reductants. Strong Vs Weak Reducing Agent

Consider the following reaction: 2 [Fe(CN)6] + Cl 2 → 2 [Fe(CN)6] + 2 Cl The reducing agent in this reaction is ferrocyanide ([Fe(CN)6] ). It donates an electron, becoming oxidized to ferricyanide ([Fe(CN)6] ). Simultaneously, that electron is received by the oxidizer chlorine (Cl 2), which is reduced to chloride (Cl ).
