The widespread use of pesticides in agriculture has led to significant environmental problems as well as complications with human health and hygiene. The current research focuses on developing the modified carbon-based nanostructured materials from Fe-doped tungsten oxide (WO₃) as a modified sensor for the analysis of synthetic growth regulators (SGR), 2,4-dichloro phenoxy acetic acid (2,4-D), and 4-cholrophenoxy acetic acid (4-CPAA) by employing cyclic voltammetry (CV). The full characterizations of Fe-doped WO₃ nanoparticles were carried out to understand their morphology, dopant concentration, atomic distribution, and valence of each element. The electro-catalytic behavior, conducting, and large surface area of the tungsten oxide were responsible for the improvement of voltammetric signals compared to nascent CPE. The effect of pH was investigated at pH 3.0 for 4-CPAA, while pH 6.0 was used for 2,4-D. From the experimental data generated electro−kinetic and activation aspects were estimated by the impact of sweep rate and temperature. The square wave voltammetric (SWV) technique was employed to investigate 2,4-D with a lesser LOD of 6.28 ×10^-8 M (2,4-D), while that for 4-CPAA, the detection limit was 9.23 ×10^-8 M (4-CPAA). The developed method can be useful for the future analysis of various SGRs.

农业中农药的广泛使用导致了严重的环境问题以及人类健康和卫生的复杂化。_{目前的研究重点是开发由铁掺杂氧化钨（WO 3} ）制成的改性碳基纳米结构材料作为改性传感器，用于分析合成生长调节剂（SGR）、2,4-二氯苯氧基乙酸（2,4 -D) 和 4-氯苯氧基乙酸 (4-CPAA)，采用循环伏安法 (CV)。_{对 Fe 掺杂 WO 3}纳米粒子进行了全面表征，以了解其形态、掺杂剂浓度、原子分布和每种元素的价态。与新生的 CPE 相比，氧化钨的电催化行为、导电性和大表面积是伏安信号改善的原因。对于 4-CPAA，在 pH 3.0 下研究了 pH 值的影响，而对于 2,4-D，则在 pH 6.0 下进行了研究。根据产生的实验数据，通过扫描速率和温度的影响来估计电动和激活方面。采用方波伏安法 (SWV) 技术研究 2,4-D，LOD 较低为 6.28 ×10 -8 ^M (2,4-D)，而 4-CPAA 的检测限为 9.23 ×10 ^-8 M (4-CPAA)。所开发的方法可用于未来各种 SGR 的分析。
