基于阴离子合成洗涤剂检测的便携式分液漏斗振荡装置

Portable Separation Funnel Vibration Device Based on Anionic Synthetic Detergent Detection

目前,我国城市存在管网混接、管网老旧等情况,导致部分含有阴离子合成洗涤剂的废水大量排入水体环境中,引起水质富营养化,严重影响水环境,因此,对阴离子合成洗涤剂检测的要求逐渐严格。为减少水样在运输过程中对检测结果产生的影响,结合便携式分光光度计,研发一种满足现场试验要求的便携式分液漏斗振荡装置尤为重要。研发的便携式分液漏斗装置能够弥补市面上分液漏斗振荡装置硬件设计方面的不足,使拆装更加便捷,氟橡胶材质底座和颈套装置固定更加牢固,也能很好地保护玻璃材质的分液漏斗,同时其占地面积小、自重轻,有固定和移动电源两种供电模式,可实现定时、调速、调频等功能,能够应用于野外等不同场景。

At present,there are mixed pipeline networks and old pipeline networks in cities at home,which lead to a large amount of wastewater containing anionic synthetic detergents being discharged into the water environment,causing eutrophication of water quality and seriously affecting the water environment.Therefore,the detection of anionic synthetic detergents requirements are becoming stricter.In order to reduce the influence of water samples on the test results during transportation,it is particularly important to develop a portable separation funnel vibration device that meets the requirements of field experiments in combination with a portable spectrophotometer.The portable separation funnel device in this study could make up for the deficiencies in the hardware design of the separation funnel vibration device on the market,to make disassembly and assembly more convenient.The separation funnel had a small footprint,light weight,two power supply modes,fixed and mobile power supply,and could realize functions such as timing,speed regulation,and frequency regulation,and could be used in different scenarios such as the field.
