The removal of nitrate and phosphate in polluted water is a challenging environmental problem. This study was designed to use a different light spectrum to enhance carbon-based metal nanocomposites adsorbent for the augmented removal of nitrate and phosphate from aqueous solution. Synthesis of aluminium oxide nanoparticle (Al₂O₃NPs)/Moringa oleifera gum activated carbon (MOGAC) based nanocomposites was conducted using sol-gel method. Incidentally, prepared nanocomposite was subject to evaluate the photocatalytic removal of nitrate and phosphate under different LED light irradiations. The microscopic image of MOGAC showed the pores on its surface, which resembles a honeycomb-like structure. The bandgap energy values of the Al₂O₃ and Al₂O₃/MOGAC were 3.16 and 3.22 eV, which corresponded to the reflectance edge of 420 nm. The surface area of Al₂O₃/MOGAC nanocomposites resolute was recorded as 176.92 m²/g^-1. Photocatalytic activity against nitrate and phosphate was carried out by the synthesized nanocomposites under the different LED light spectrum. The red LED light spectrum and 10 mg/L of nanocomposite removed nitrate and phosphate ions up to 94% and 95% after 105 minutes and 75 minutes of irradiation, respectively. Overall, the Al₂O₃/MOGAC nanocomposites maintained good stability after four cycles of nitrate and phosphate reduction.

去除污水中的硝酸盐和磷酸盐是一个具有挑战性的环境问题。这项研究旨在使用不同的光谱来增强碳基金属纳米复合材料吸附剂，以增强从水溶液中去除硝酸盐和磷酸盐的能力。采用溶胶-凝胶法合成了氧化铝纳米颗粒（Al ₂ O ₃ NPs）/辣木胶活性炭（MOGAC）基纳米复合材料。顺便提及，制备的纳米复合材料经受了在不同LED光照射下光催化去除硝酸盐和磷酸盐的评估。MOGAC的显微图像显示其表面上的孔，其类似于蜂窝状结构。Al ₂ O的带隙能值₃和Al ₂ O ₃ / MOGAC分别为3.16和3.22 eV，对应于420 nm的反射率边缘。记录的Al ₂ O ₃ / MOGAC纳米复合固溶体的表面积为176.92 m ² / g ^-1。合成的纳米复合材料在不同的LED光谱下具有对硝酸盐和磷酸盐的光催化活性。在照射105分钟和75分钟后，红色LED光谱和10 mg / L的纳米复合材料分别去除了高达94％和95％的硝酸根和磷酸根离子。总体而言，在硝酸盐和磷酸盐还原的四个循环后，Al ₂ O ₃ / MOGAC纳米复合材料保持了良好的稳定性。
