Abstract

The invention discloses a glass fiber subjected to surface treatment and a preparation method thereof, and application of the glass fiber to cadmium ion detection and water treatment. The glass fiber is prepared from a common glass fiber serving as a raw material and the common glass fiber is treated by a silane coupling agent and a heavy metal chelant to form the glass fiber. The common glass fiber is treated by the silane coupling agent to ensure that chemical bonding is performed on the silane coupling agent and the surface of the common glass fiber; and the glass fiber treated by the silane coupling agent is treated by the heavy metal chelant to ensure that chemical reaction is performed on the heavy metal chelant and the silane coupling agent to realize bonding so as to form the glass fiber subjected to surface treatment. The preparation method of the glass fiber subjected to surface treatment has important application value in the field of detection and treatment of heavy-metal-containing wastewater, and particularly has the wide application prospect in the serious heavy metal pollution area.

Description

technical field [0001] The invention relates to the technical field of heavy metal detection and treatment, in particular to a surface-treated glass fiber and a preparation method thereof, and also relates to the application of the glass fiber. Background technique [0002] Many heavy metal ions can cause very large toxic effects on the human body and the environment, especially cadmium ions and mercury ions are the most harmful to the environment and the human body. For example, cadmium is recognized as a metal that is highly toxic and carcinogenic to humans and animals. Excessive concentration of cadmium ions will cause a series of physiological diseases in the human body, such as gastrointestinal disorders, muscle spasms, bone damage, neuralgia, etc. Cadmium pollution can occur with natural dissolution phenomena such as rocks and soils. At the same time, with the expansion of human metallurgical industry, especially the rapid development of electroplating and battery indu...
