PENURUNAN KADAR ION LOGAM KROMIUM PADA LIMBAH INDUSTRI SARUNG SAMARINDA DENGAN MENGGUNAKAN METODE ELEKTROKOAGULASI
Abstrak: The reduction of
chromium concentration in Samarinda sarong wastewater by electrocoagulation
method has been carried out. The research used Atomic Absorption
Spectrophotometer (AAS) as an instrument determination level. To determination
the optimum levels of each parameters by large percent qualified of
electrocoagulation process with used variation of series parameters such as
time contact, variation voltage and the distance of electrode. The result of
research showed that degradation and is big of elimination percent of metal of
Cr have an in with the effect of time contact, voltage and also distance of
electrode at optimum hence in getting result of final concentration
successively 31,250; 21,325 and 17,925 ppm of concentration early 50,650 ppm.
Big of elimination percent of exclusion at optimum parameter in getting result
successively 38,302; 57,897 and 64,610 %. Resulted in this research obtained
optimum time contact is 30 minutes, optimum voltage is 4,5 volt and optimum
distance of electrode is 1 cm.
