The Ouw Natural Clay Impregnation Using Titanium Dioxide as a Rhodamine B Dyestuff Degrader

Abstract

This study aims to determine the effect of calcination temperature on Titanium dioxide impregnated Ouw Natural Clay (LAO) on the degradation of Rhodamine B dye. The calcination temperature used was 200, 300, and 400 °C. Their radiation was carried out with 3x8 watt UV lamps and sunlight. The degradation percentage of Rhodamine B dye produced by LAO-TiO2 calcined at a temperature of 200, 300, and 400 °C with sunlight were 98.80%, 98.87%, and 96.07%, respectively. The degradation percentage of Rhodamine B dye produced by LAO-TiO2 calcined at temperatures of 200, 300, and 400 °C with the help of UV light were 96.01%, 97.41 %, and 97.18%, respectively.

The Interaction Mechanism of Papaya Seeds (Carica papaya L.) as a Natural Coagulant and Remazol Red Under Different pH Conditions

“…This dye has high stability so it is difficult to degrade naturally (Safitri & Rahmayanti, (2020); Maya Rahmayanti, Nurhikmah, & Larasati, (2021). Batik wastewater containing remazol red dye if discharged into the environment can last a long time and accumulate to a certain concentration level and cause negative impacts on the environment (Pembayun & Rahmayanti, 2020); (Pambudi, Prayogo, Nadjib, & Ediati, (2021); Tanasale, Sutapa, & Topurtawy, (2014); Bijang, Nurdin, Latupeirissa, Aziz, & Talapessy, (2022).…”
