摘要:
随着城市供水水质安全保障需求的日益提升，实时监测与应急响应能力成为关键。基于离子色谱分析技术，研发了一款便携式水质分析仪，旨在解决城市供水水质快速检测难题。全面评估了该分析仪在实验室环境及45 ℃高温、-15 ℃低温等极端条件下的性能，结果表明，其在高低温环境下关键性能稳定，检测准确性与现场适用性优异，可满足多样化检测需求。实际水样测定进一步验证了其对水质离子成分的精准检测能力。同时，针对饮用水中高氯酸盐的快速检测需求，建立了便携式离子色谱检测方法。经系统优化色谱柱类型、淋洗液配方及流速等参数，确定采用2 mm AS19色谱柱、50 mmol/L KOH淋洗液、0.25 mL/min流速作为测定水中高氯酸盐含量的最佳条件。方法学验证表明，该方法线性相关系数>0.999，检出限1.00 μg/L，定量限3.50 μg/L，加标回收率91.5%~109.0%，具有灵敏度高、准确性好的特点，为饮用水安全应急监测提供了有力的技术保障。
Abstract:
With the growing demand for ensuring the safety of urban water supply quality, real- time monitoring and emergency response capabilities have become crucial. In this study, a portable water quality analyzer was developed based on ion chromatography technology, aiming to solve the problem of rapid detection of water quality in urban water supply. Comprehensive performance tests were carried out in laboratory environments and under extreme conditions, such as a high temperature of 45 ℃ and a low temperature of -15 ℃. The results indicated that the analyzer’s key performance remains stable in high and low temperature environments, with excellent detection accuracy and on-site applicability, thus being able to meet various detection requirements. Tests on actual water samples further verified its precise detection capability for ionic components in water. Meanwhile, in response to the need for rapid detection of perchlorate in drinking water, a portable ion chromatography detection method was established. Through systematic optimization of parameters such as column type, eluent formula, and flow rate, it was determined that the optimal conditions for determining perchlorate concentration in water were: a 2 mm AS19 chromatographic column, a KOH eluent concentration of 50 mmol/L, and a flow rate of 0.25 mL/min.Method validation showed that this method had a linear correlation coefficient greater than 0.999, a detection limit of 1.00 μg/L, a quantification limit of 3.50 μg/L, and spike recovery rates ranging from 91.5% to 109.0%, demonstrating high sensitivity and good accuracy. It could provide a strong technical guarantee for emergency monitoring of drinking water safety.
