SULPHATE POTASIUM EXTRACTION FROM BANANA STEM ASH WITH BLEACHING EARTH WASTE LIQUID
ABSTRACT: Sulphate potassium
is one of the important chemistry compound for industrial at our country,
usually for fertilizerindustry. Therefore, necessary done sulphate potassium
maker watchfulness from various ingredient that containsulphate potassium
compound. Among others with extract banana stem ash. Watchfulness methodology
that is withmix banana stem ash with aquadest (20 gram ash/1 water litre) in
temperature 100oc during 30 minutes and stirringrotation 300 rpm. Ash extract
that got reaction with sulphuric acid found of liquid waste bleaching earth.
Bleachingearth with certain rate of flow (5,10,15,20) ml/second is putted into.
After achieved steady conditon, process iscontinued up to 15 minutes. Result is
analyzed to determine sulphate potassium conversion. Based on
watchfulnessresult that done, best condition is got in temperature 60oc with
speed emits bleaching earth 10 ml/second, producesulphate potassium degree as
big as 20184 mg/litres and conversion that got as big as 88,061%.
