A novel pH‐dependent sensitive and convenient assay was proposed for the determination of Cd2+and Al3+in aqueous medium using the sodium dodecyl sulfate (SDS) modified AgNPs as signal probes. In different pH values, the probe showed a visually detectable color change based on the strong interaction of Cd2+and Al3+with SDS. The color of SDS‐AgNPs solution would change from bright yellow to purple red in the presence of Cd2+at pH 9.8, and to reddish brown in the presence of Al3+at pH 5.5. Under the optimum experimental conditions, the ratio ofA580 nm/A390 nmof SDS‐AgNPs gradually increased with increasing of Cd2+, and a good linear relationship was achieved when Cd2+concentration ranging from 4.2×10−8M to 3.0×10−6M. Linear decreasing ofA390 nmrelated to Al3+concentration was over the range of 3.6×10−8M to 2.0×10−6M. The limit of detection was as low as 11.2 nM Cd2+and 7.2 nM Al3+, respectively. Importantly, it has been successfully applied to detect Cd2+and Al3+in real samples.
