Abstract

The invention relates to a preparation method of a green solvent modified zeolite phenol sorbent. The preparation method comprises the following steps of: a, adjusting the pH value of a 1.0-1.2wt% hexadecyl-3-methylimidazole chloride solution to be alkali, thereby preparing a modifier solution; b, mixing zeolite and the modifier solution prepared in the step a; c, carrying out solid-liquid separation in a centrifugal machine to obtain a sediment, cleaning the sediment by using distilled water, then, centrifuging, and repeating the steps until a supernatant liquid is checked by using a silver nitrate solution to have no white sediment; and d, drying a solid substance by using an electrothermal blowing dry box to obtain modified zeolite, wherein the solid substance is obtained through separation in the step c. The method has the following advantages: raw materials are easily available, and the method is simple and convenient to operate; and the prepared phenol sorbent is environmental-friendly and pollution-free, and the absorption capacity of the phenol sorbent is increased by over 10 times than that of common zeolite.

Description

technical field

[0001] The invention relates to a phenol adsorbent, in particular to a green solvent modified zeolite phenol adsorbent and a preparation method thereof. Background technique

[0002] Phenol and phenolic derivatives are both environmental pollutants. Many industries, such as petroleum, petrochemical, coal conversion, pesticides, coatings, pharmaceuticals, plastics, paper and other industries, discharge phenolic compounds into the environment. Phenol is discharged into groundwater, surface water and soil through various channels, which has brought serious harm to the ecological environment. There are many physical, chemical and biological methods for removing phenol pollutants in water. Activated carbon adsorption, biodegradation, chemical oxidation, solvent extraction, resin and membrane ion exchange are more commonly used methods. In addition, there are also selective adsorption properties of clay minerals, fly ash, coal, waste, and chitin to adsorb phenol i...
