Catalytic Removal of Heavy Metals from Waste Water by Pumpkin Pectin-Containing Nanomaterials-Based Enzyme

Over the past decades, the growing industrialization caused continuously increased release of heavy metal into environment. Through the food chain, heavy metals can be enriched in the body, causing serious harm. The removal and recycling of heavy metals are of great significance to environment protection, health concern as well as resource reuse. Pectic materials are available from a variety of natural sources and can be used as versatile adsorbents for heavy metal. Enzyme-based biocatalysts are one of the largest and commercially successful groups of catalysts. Integration of nanomaterials in the applications results in significant improvement of sensitivity, stability and other analytical characteristics. Thus, new functional nanomaterials are key components of numerous biosensors. However, due to the great variety of available nanomaterials, they should be carefully selected according to the desired effects. For the correction of pathological conditions of the human body, the prevention and rehabilitation of intoxication, the development of enterosorbents is necessary, one of which is various pectin products. Based on the conducted experiments, the regime parameters of obtaining pumpkin pectin-containing extract by the enzymatic method were established.
