AB  - The present investigation reports a comprehensible and responsive strategy for 
      identifying atrazine in several conditions using an extensive electrochemical 
      method. CdS Quantum dots were synthesized via a greener approach, and their 
      formation was endorsed by numerous characterization techniques such as FTIR, SEM, 
      Raman, UV-Vis, and XRD. Owing to the splendid electrocatalytic behavior, Green 
      CdS quantum dots (QDs) of crystallite size  approximately 2 nm was opted as the sensor material 
      and were, therefore, incorporated on the bare carbon paste electrode's surface. 
      The developed sensor demonstrated an impressive outcome for atrazine sensing 
      accompanied by superior selectivity and sensitivity. The lower detection limit 
      (LLOD) of 0.53 muM was attained using the developed sensor in a linear 
      concentration range of 10-100 muM. Furthermore, the practical pertinence of the 
      developed sensor was examined on distilled water, wastewater, and fresh liquid 
      milk, resulting in a tremendous retrieval of atrazine (91.33-99.8%).
