Description

一种在高温高压消煮过程中防止比色管内液体喷溅的新方法
技术领域:
本发明涉及一种在高温高压消煮过程中防止比色管内液体喷溅的封口方法,可以用于紫外分光光度法测定河流水总氮、总磷时,使用压力锅消煮过程中防止液体喷溅出管外而造成实验误差。
背景技术:
氮、磷是组成生物体结构,对生物生长、发育、生殖等过程起促进作用的元素,同时也是引起水体富营养化的主要影响因素。近年来随着经济的发展,人类活动的加剧,大量含氮,磷的城市污水,工农业废水等随着降雨或地表径流进入河湖等自然水体,使水体中氮、磷迅速富集,导致某些藻类过渡繁殖,溶解氧含量降低造成水质恶化。因此,研究水体氮、磷含量的变化特征对深入认识河湖富营养化问题至关重要,总氮、总磷也早以作为水质日常监测的常规指标之一。
为了研究水体的富营养化水平,快速准确的测定总氮、总磷的质量浓度尤为重要。但在实际的水样测定中,为了防止在消煮过程中液体由于高温高压产生的喷溅从而影响实验的准确度,常常需要在比色管放入压力锅前塞紧磨口赛并用纱布及纱绳裹紧管塞。这个过程费时费力,且样品编号必须书写于管身,不方便识别,大大影响了实验的速度。因此,实际实验中需要一种新的方法来简化实验步骤,加快实验进度,
发明内容:
本发明利用封口膜和橡皮筋,可以在紫外分光光度法测定总氮、总磷时,用压力锅进行消煮过程中防止液体喷溅,且封口膜上易于书写,方便编号,大大简化了实验步骤,加快了实验进度。
本发明主要由以下几部分组成:(1)封口膜:主要功能是防水透气,可达到防止液体喷溅的效果;(2)橡皮筋:用于捆绑封口膜于比色管上,达到密封效果。
本发明的使用过程为:紫外分光光度法测定总氮、总磷时,在盛有样品的比色管放入压力锅前,用封口膜盖覆在比色管上并用橡皮筋捆绑严密,并在封口膜上书写编号后进行下一步实验操作。
本发明的特点为:封口膜和橡皮筋均为实验室常见耗材,价格低廉且容易购买,使用后可作为垃圾丢弃,方便快捷。用橡皮筋将封口膜捆绑在比色管管口上,在高温高压的条件下,封口膜可以起到防止比色管内的液体喷溅到管外,且具有透气功能,及时平衡管内外的压力。同时封口膜上方便书写编号,便于样品的快速识别。本发明代替了传统方法中利用磨口塞塞紧管口并用纱布和纱绳裹紧管塞的方法,具有方便快捷的特点,在保证实验准确性的前提下加快了实验进度。

具体实施方式:
1.采用不同封口方法测定总氮、总磷的对比实验
为了验证本发明的实用性,选取相同河流水样品进行总氮、总磷测定,采用不同的封口方法进行对比实验。两种封口方法分别为本发明和传统磨口塞塞紧管口并用纱布和纱绳裹紧管塞的方法。
2.具体实施过程
选择相同的河流水样品,分AB两组实验进行,每组设6个平行;A组样品用压力锅进行消煮步骤前采用本发明的封口方式封口;B组样品在用压力锅进行消煮步骤前采用传统的封口方式封口。两组样品均在相同的实验条件下采用紫外分光光度法测定总氮和总磷含量。实验结果表明:采用本发明封口方法的A组总氮浓度为23.246±0.369,平均值为23.487,总磷浓度为1.414±0.189,平均值为1.501;采用传统封口方法的B组总氮浓度为23.209±0.452,平均值为23.490,总磷浓度为1.392±0.201,平均值为1.512;可见,采用本发明的封口方法和传统封口方法所得到的实验结果基本一致,说明本发明能够在高温高压消煮过程中有效防止液体喷溅,同时有着操作简单,方便编号等优点。
