    Case Study

    Preparation of Cu(II)-Doped Manganese Sulfate Monohydrate Crystals

    Sagar R, et al, Optical and Quantum Electronics, 2021, 53, 1-10.

    Single crystals of Cu (II) sulfate doped manganese sulfate monohydrate were grown successfully by slow evaporation solution technique. The increase in Cu (II) sulfate incorporation increases size and the rate of crystal growth. The single crystals exhibit good transmission values in the range above 400 nm and it magnitude varies anomaly as a function of Cu(II) concentration. It is seen from thermal analysis that the decomposition temperature of MnS: Cu(II) crystals increases with increase in Cu(II) concentration.
    Crystal growth
    · The single crystals of Cu (II) doped Manganese sulfate were grown by using manganese sulfate and copper (II) sulfate as a starting materials. The saturated solution of both sulfates ware prepared by adding powder up to its solubility limit with continuous mixing.
    · The saturated solutions were repeatedly fltered to reduce the impurity level. The concentration of 10, 20 and 30% of copper sulfate was incorporated in manganese sulfate saturated solution mentioned as Cu10:MnS, Cu20:MnS and Cu30:MnS respectively as a dopant and mixed using magnetic stirrer to homogenize.

    Safety and Effectiveness of Manganese Sulfate Monohydrate as Feed Additive

    EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP). EFSA Journal, 2013, 11(10): 3435.

    Manganese sulfate monohydrate is commonly used as an additive in animal foods, fungicides, and as a precursor to other manganese salts. Manganese sulfate monohydrate is one of the safe sources of manganese for all animal species/categories. Important conclusions from relevant research on the safety and effectiveness of manganese sulfate monohydrate as a feed additive for all species include:
    · Dietary manganese does not appear to cause any adverse health effects in the population and has not been shown to pose a risk at usual intake levels.
    · Manganese intake from consuming animal tissues and products is low and does not affect consumer safety.
    · The use of manganese sulfate monohydrate in animal nutrition does not affect consumer safety as long as the current authorized maximum total content of manganese in feed is observed.
    · Handling of manganese sulfate monohydrate poses a risk of inhalation exposure to users. Manganese sulfate monohydrate is not irritating to the skin, but it can be irritating to the eyes.
    · The use of manganese sulfate monohydrate in animal nutrition for all animal species has no environmental impact as long as the current authorized maximum total content of manganese in feed is observed.
