摘要：

The rapid detection of uranium in water environment is of great significance for water purification and uranium recovery. In this work, ultrathin nickel hydroxide (Ni(OH)2) nanosheets was in-situ growth on carbon nanotubes (CNTs) to form Ni(OH)2@CNTs electrode for uranyl ion (UO22+) detection. The as-prepared Ni(OH)2@CNTs shows good sensitivity in the electrolyte containing UO22+ with the limit of detection of about 8.603 ppb. Moreover, the Ni(OH)2@CNTs also exhibits significant selectivity for UO22+ in complex wastewater with several interfering cations and anions. This work provides a novel Ni(OH)2@CNTs electrode for UO22+ detection from uranium-containing water.
