摘要
摘要：研制了一种利用汞膜电极对近海海水中重金属离子进行检测的船载检测装置。海水中Cd2 +和Pb2 +的自动测定无需人工干预。废液收集在回收袋中进行后续处理，防止环境污染。测量的准确性和稳定性都经过了彻底的检验。在标准溶液浓度为5 μg L - 1的条件下重复测试10次，Pb2 +的相对标准偏差为7.02%，Cd2+的相对标准偏差为2.65%。建立了Cd2 +和Pb2 +的线性校准曲线，检测限均为0.31 μ L - 1。最终，该船载检测装置成功用于海水中Cd2 +和Pb2 +的原位测定。
Determination of Cd2+ and Pb2+ in seawater using a shipborne detection device.
A shipborne detection device has been developed for the detection of heavy metal ions in offshore seawater, utilizing a mercury film electrode. The automatic determination of Cd2⁺ and Pb2⁺ ions in seawater can be conducted without any manual intervention. Waste solutions are collected in a recycling bag for subsequent treatment, thereby preventing environmental pollution. The accuracy, as well as the stability of the measurements, were thoroughly examined. The relative standard deviation for Pb2⁺ was determined to be 7.02% after conducting 10 repeated tests using a standard solution concentration of 5 μg L⁻1 and the relative standard deviation of Cd2+ is 2.65%. Linear calibration curves have been established along with detection limits of 0.31 μg L⁻1 for both Cd2⁺ and Pb2⁺ ions. Ultimately, this shipborne detection device was successfully employed for the in-situ determination of Cd2⁺ and Pb2⁺ ions in seawater.
