Arsenic is regarded as a carcinogenic heavy metal that is exceedingly harmful to ecosystems. Protracted exposure to arsenic is extremely threatening to life since it can have major health impacts. The establishment of simplistic, affordable techniques is necessary to identify the existence of arsenic in water and the food supply; and early recognition of residues of activated arsenic is crucially significant. In terms of achieving the above, a reliable strategy for the simultaneous determination of As³⁺ ion in standard and actual ecological samples was established. It involved the modification of a glassy carbon electrode with the multilayer deposition of La_0.95Ce_0.05MnO₃ (LCMO) nanostructures which was conveniently prepared by hydrothermal processes, as well as the outstanding electrocatalytic performance and extremely high anti-interference electrochemical sensing of As³⁺ ion with LCMO at neutral pH media. The various physicochemical approach is performed to investigate the ultrafine nanosized morphological characteristics of LCMO substrate. A sequence of interference assays was conducted to verify the process, and no overt interference from typically conflicting compounds was reported in As³⁺ion detection. Moreover, LCMO/GCE reveals great repeatability, stability, and reliability. Arsenic identification possesses a continuous range of 0.1–20 µmolL⁻¹ under optimal settings, with a detection limit of 0.165 µmolL⁻¹ and a sensitivity of 0.356 µA/µmolL⁻¹. Under optimal scenarios, this electrochemically fabricated nanotextured LCMO/GCE is also suitable for the sensing and assessment of arsenic in a real sample of water. To reliably detect arsenic in the existence of inherent hazardous metals and organics in aqueous matrices, significant attempts are still designed to establish electrode materials and analytical techniques.

砷被认为是一种致癌重金属，对生态系统危害极大。长期接触砷会对生命造成极大威胁，因为它会对健康产生重大影响。有必要建立简单的、负担得起的技术来确定水和食物供应中砷的存在；活化砷残留物的早期识别具有至关重要的意义。为实现上述目标，建立了同时测定标准和实际生态样品中 As ^{3+离子的可靠策略。}_{它涉及通过多层沉积 La 0.95} Ce _0.05 MnO ₃对玻碳电极进行改性（LCMO）纳米结构可以方便地通过水热法制备，以及在中性 pH 介质下用 LCMO对 As ³⁺离子具有出色的电催化性能和极高的抗干扰电化学传感。采用各种物理化学方法研究 LCMO 基板的超细纳米形态特征。进行了一系列干扰测定以验证该过程，在 As ³⁺离子检测中没有报告来自典型冲突化合物的明显干扰。此外，LCMO/GCE 显示出出色的可重复性、稳定性和可靠性。砷鉴定在最佳设置下具有 0.1–20 µmolL ^-1的连续范围，检测限为 0.165 µmolL^-1和 0.356 µA/µmolL ^-1的灵敏度。在最佳情况下，这种电化学制造的纳米纹理 LCMO/GCE 也适用于检测和评估真实水样中的砷。为了可靠地检测含水基质中存在的固有有害金属和有机物中的砷，人们仍在进行重大尝试以建立电极材料和分析技术。
