Disadvantages of Silver-Loaded Activated Carbon
Silver-loaded activated carbon is a functional purification material with silver ions attached to common activated carbon for antibacterial and deodorizing purposes. Despite its sterilization performance, it has obvious drawbacks in practical application, limiting its large-scale and long-term use in water treatment and air purification.
The most prominent problem is the loss of silver ions. Under long-term water immersion and continuous flow scouring, the loaded silver ions will gradually separate and dissolve out. This not only weakens the antibacterial effect and shortens the service life sharply, but also leads to excessive silver residue in water, failing to meet high-standard drinking water safety requirements. In addition, silver particles block part of the micropore structure, greatly reducing the original adsorption capacity for formaldehyde, residual chlorine, odor and organic pollutants.
This material also features poor acid and alkali resistance and unstable performance in complex water quality environments. It is much more expensive than ordinary activated carbon yet wears out faster, raising replacement costs. Furthermore, waste silver-loaded carbon is classified as special hazardous waste with complicated disposal procedures and potential environmental risks.
