The prepared solid-phase extraction material functions in the separation and enrichment of PPCPs by means of a variety of forces with a high extraction rate. The extraction rate is basically maintained between 85% and 105%, and acidic, alkaline, neutral and amphoteric substances is capable of being selectively separated.

Abstract: This invention has fundamentally rewritten the technological history of electric heating blanket. The main body of this new type of electric heating blanket provided by this invention does not contain wires with metal components, it completely eradicates the phenomenon of contact sparking, burning, and conflagration disasters caused by the fracture of wires with metal components due to stretching and folding during usage. This new type of electric heating blanket does not contain wires with metal components, which can conserve metal resources. This new type of electric heating blanket operates at a voltage of 24 volts, which is consistent with the international standard for safe voltage. It will never cause injury to humanity due to electric shock during the use of this new type of electric heating blanket. The main body of this electric heating blanket can be washed by hand or in a washing machine since it does not contain wires with metal components.
