Abstract:
Water contamination is a major worldwide issue that endangers human and environmental
health at risk. Water supplies are rendered unfit for intake or reuse by pollutants like as
organic waste & heavy metals, necessitating efficient wastewater treatment techniques. For
this issue, several solutions have been put forth, namely membrane separation, adsorption,
& photocatalysis. Photocatalysis is an innovative method in which nanoadsorbent particles degrade tetracycline (TC) without the usage of any further treatment.
Antibiotic usage has significantly increased recently because of bacterial infectious
diseases that affect both humans and animals. But this use is resulting in harmful effects to
the water quality, aquatic environment, and soil microbial communities. In this work, I
have focused on the tetracycline removal from water using advanced oxidation process by
synthesizing efficient nanohybrids. The most effective way to treat water so that it can be
used again for irrigation and drinking is the advanced oxidation process. These nanohybrids
act both as photocatalyst and adsorbent thereby enhancing the percentage degradation of
tetracycline. This study created a new photo-adsorbent via a hydrothermal and in-situ
technique. Results of X-ray diffraction and scanning electron microscopy show that photoabsorbents are synthesized efficiently. UV-Visible spectrophotometry is used to evaluate
degradation performance. By using 100 mg of CdS@ZIF-67 hybrid, 96% of tetracycline
has been successfully degraded in 110 minutes. By increasing the quantity of CdS,
percentage removal of tetracycline has been increased. CdS is found to be potential highly
efficient photocatalyst for tetracycline degradation.
