AI Technical Summary

Technical Problem

Existing nano-adsorbents have poor stability and low adsorption capacity, making it difficult to effectively remove heavy metal ions from water.

Method used

Calcium silicate hydrate-based nano-adsorbents are used to modify calcium silicate hydrate nanoparticles by doping them with iron ions, magnesium ions and aluminum ions, and polycarboxylate water reducer is used as a dispersant to optimize the nanoparticle structure and dispersion effect.

Benefits of technology

The structural stability and adsorption capacity of the nano-adsorbent are improved, the adsorption efficiency of heavy metal ions is significantly enhanced, and particle agglomeration and precipitation during long-term storage are avoided.

Abstract

The present invention discloses a calcium silicate hydrate-based nano-adsorbent and a preparation method and application thereof. The nano-adsorbent is a composite of modified calcium silicate hydrate nano-particles and a dispersant. The modified calcium silicate hydrate nano-particles include calcium silicate hydrate nano-particles and iron ions, magnesium ions and aluminum ions doped in the calcium silicate hydrate nano-particles. After structural modification, the particle size of the calcium silicate hydrate-based nano-adsorbent is reduced, the specific surface area is greatly increased, and the number of adsorption sites on its surface that can adsorb heavy metals is significantly increased, thereby improving its adsorption efficiency and adsorption capacity for heavy metal ions.
