Contamination by Remazol Red Brilliant Dye and Its Impact in Aquatic Photosynthetic Microbiota

Abstract

The purpose of this work was to evaluate the heterogeneity and diversity of algae according to an aquatic environment polluted by Remazol Red Brilliant dye. Methodology followed Winogradsky columns technique, which describes a microecosystem in a glass container. Two columns were prepared: one control and another with Remazol Red Brilliant dye simulating a contaminated environment. The experiment was under illumination to provide light energy to photosynthetic organisms and alteration in two columns were observed and quantified: algae development and color changes. Results demonstrated that pH remained constant in control column; however the initial pH changed in contaminated column. A higher pH observed at the bottom after 48 days showed microbial activity in dye biodegradation, which was corroborated by minor absorbance value at Remazol Red Brilliant peak (541.5 nm). Moreover, control column presented higher algae growth since the beginning owing to the dye absence and 12 different families were identified in two Winogradsky column. This analysis concluded that, despite the greater diversity found in B, algae biomass production was much smaller compared to column without the dye. Therefore, Remazol Red Brilliant presence would affect the food chain in aquatic environments and consequently causes an ecological imbalance by the textile effluent impact.

Plasma-modified wood sawdust waste for the removal of reactive blue II anionic dye from aqueous solution

“…Most often, the effluents discharged by these industries into the aquatic environment are sources of serious pollution problems [1]. The site of the discharged wastewater containing dyes cause the obstruction of light necessary for photosynthesis of aquatic plants, which reduces the growth of algae and leads to ecological imbalance in the aquatic ecosystem; in addition, these pollutants also have toxic and carcinogenic effects in humans [2,3] At a time when international community is seriously cornes about clean water, which is more and more polluted, rare and overexploited according to the report of the world water day of march 22, 2022, it is becoming more that urgent to build up green methods, efficient and inexpensive solutions for the 3.6 billions peoples in the world who nowaday do not always have access to modern methods of water treatment. Many scientists are paying close attention to this issue, in line with the increasingly stringent standards for toxic discharge.…”

Adsorption of Crystal Violet onto Adsorbents Derived from Agricultural Wastes: Kinetic and Equilibrium Studies

“…In recent time, there is a growing interest and concern over contamination of the aquatic environment by dyes. This is because the release of dyes into aquatic environment causes reduction in the growth of algae due to obstruction of light required for photosynthesis, which subsequently leads to ecological imbalance in the aquatic ecosystem (de Sousa et al, 2012). Contamination of aquatic environment by dyes has also been shown to have toxic, carcinogenic, and aesthetic effects on humans (Ratna and Pahdi, 2012).…”

Perbandingan Aktivitas Reaksi Fotodegradasi Remazol Red dengan TiO2 Anatas 50%-Rutil 50% dan TiO2 Anatas Tersupport AgI

“…Ternyata sebanyak 2%-50% zat warna yang digunakan pada proses pewarnaan bahan tekstil tidak menempel pada serat kain, sehingga zat warna tersebut dapat masuk ke dalam perairan melalui limbah yang dihasilkan (Gustiani, et al, 2014). Adanya ikatan azo (-N=N-) pada zat warna azo menjadikannya lebih mudah larut dalam air dan memiliki stabilitas yang tinggi (de Sousa, et al, 2012). Oleh karena itu, limbah tekstil memerlukan penanganan yang rumit dan membutuhkan beberapa langkah sampai limbah tersebut aman dan tidak memberikan dampak negatif ketika dilepas ke perairan Untuk mengantisipasi terjadinya dampak negatif dari zat warna azo bagi lingkungan maupun kesehatan manusia, dapat dilakukan dengan cara menghilangkan kandungan zat warna azo dari limbah industri.…”
