ANALISIS KANDUNGAN KLORIN PADA AIR TEH CELUP BERDASARKAN SUHU DAN WAKTU PENCELUPAN TAHUN 2013
ABSTRACT: Tea is the most
consumed beverage either cold or hot. One kind of them is bag tea products. Tea
bag is wrapped in smooth porous paper and heat resistant. In general, the paper
uses chlorine as a bleach, it is the reason for necessary to study the chlorine
content in water of tea bag.
The purpose of this study was to determine the chlorine content in water
of tea bag based on temperature and time. The kind of this study is descriptive
survey. The object of study is the water of tea bag mixing in drinking water
then examined in laboratorium of Balai Teknik Kesehatan Lingkungan Dan Pemberantasan
Penyakit Menular Kelas I Medan by using spectrophotometric method.
Based on the findings, there is the chlorine content of tea bag water at
40 0 - 100 0 C with immersion time respectively 1 minutes, 3 minutes and 5
minutes. The survey results revealed that the chlorine content increased by the
increasing of temperature and time. The chlorine content is 1.35 mg/250 ml in
temperature of 90 0 c with 3 minutes immersion and chlorine content 0.2817
mg/250 ml in temperature of 80 0 c with 3 minutes.
Hence, it is concluded that the increasing of temperature and time will
increase the chlorine in the tea bag water. It can be harmful health both in
short and long term. According to Permenkes RI No. 492/Menkes/Per/IV/2010 that
chlorine levels in drinking water is 1.25 mg/250 ml. It is suggested for
