Remazol Brilliant Violet 5R

The ability of agricultural waste materials to remove synthetic dyes such as Remazol Brilliant Violet 5R (RBV-5R) and Remazol Brilliant Blue R (RBBR) from aqueous solutions was investigated. Dyes are a major source of water contamination that not only cause significant damage to water bodies but also have a negative effect on human health due to their high toxicity and carcinogenic nature. Agricultural wastes are renewable adsorbents because they are readily available and inexpensive, and they can also be used instead of conventional activated carbon. As a result, the removal of RBV-5R and RBBR from dye solutions by adsorption onto treated adsorbent was investigated in this review. The two best adsorbents out of ten were selected via a screening process with RBBR as the test dye. The key adsorbents in this analysis were coconut shells and mango seeds, which had the highest removal rate as compared to others. The experiment was continued with the chosen adsorbent to see how different initial dye concentrations, adsorbent dosage, contact time, pH, and particle size affected dye adsorption. The results show that different parameters have different effects on the removal rate and adsorption potential of the adsorbent. The adsorption of dye from aqueous solution onto adsorbent was investigated using Fourier transform infrared spectroscopy (FTIR) to investigate the functional groups of the adsorbent before and after the adsorption operation, and it was discovered that the functional group affected the effectiveness or removal rate as well as the adsorption capability of adsorbents. According to the findings, 5 gram mango seeds can extract 85.54 percent of RBV-5R with adsorption power of 1.26 mg/g. For 21 hours, coconut shells removed 74.39 percent of RBBR with an adsorption capacity of 8.01 mg/g. The findings indicated that these agricultural wastes could be useful as an alternative adsorbent for removing dye from aqueous solutions.

The potential of agricultural waste materials for the removal of synthetic dye, Phenol Red (PR) and Remazol Brilliant Blue R (RBBR) from aqueous solution was investigated. One of the major pollutants of water pollution, dyes, which not only result in enormous damage to the water body but also impact the organism's health, as it is highly toxic and carcinogenic by nature. Agricultural wastes are sustainable adsorbents since they are availability and low cost, which can also replace the traditional activated carbon. Therefore, this study investigated the removal of PR and RBBR from dye solution by adsorption onto the treated adsorbent. Two best out of ten adsorbents were chosen through a screening process using RBBR as a tested dye. Coconut shells (Cocos nucifera) and ambarella peels (Spondias dulcis) were selected as the main adsorbent of this study since they achieved the highest removal rate compared to others. With the selected adsorbent, the experiment was continued to study the effect of different initial dye concentration, adsorbent dosage, contact time, pH, and particle size on dye adsorption. Results show that different parameters can affect the removal rate and adsorption capacity of adsorbent in a different way. The adsorption of dye from aqueous solution onto adsorbent was evaluated using Fourier transform infrared spectroscopy (FTIR) to investigate the functional groups of adsorbent before and after the adsorption process, and it found that the functional group would affect the effectiveness or removal rate and adsorption capacity of adsorbents. The present study indicates that 99.82% of PR with an adsorption capacity of 1.05 mg/g can be removed by 5-gram ambarella peels. While coconut shells had removed 75.78% of RBBR with an adsorption capacity of 7.96 mg/g for 21 hours. The results proved that these agricultural waste were promising materials as an alternative adsorbent for the removal of dye from aqueous solution.

Manganese substituted iron titanate was successfully synthesized and characterized by x-ray diffraction and Fourier transformed infra-red to investigate the composition and to identify the chemical compound of this unique architecture. The materials were tested for adsorption of remazol brilliant blue R (RBBR) aqueous solution. The adsorptions were investigated at different pH which are pH 3, 4, dye concentration and manganese substituted iron titanate dosage. It was found that synthesized manganese substituted iron titanate particles can adsorbed 99% of 100 ppm RBBR dye at pH 2.

Abstract Remazol Brilliant Blue R (RBBR) is a widely used carcinogenic and toxic dye. This study focused on RBBR dye from aqueous solution using potassium permanganate, cetyltrimethylammonium bromide (CTAB) modified, and unmodified Yarrowia lipolytica biomass as biosorbent. RBBR dye biosorption studies were carried out as a function of pH, initial dye concentration, biosorbent dose, contact time, and temperature. The pH of the aqueous solution strongly influenced the biosorption percent of RBBR dye. The highest dye biosorption capacity yield was obtained at pH 2-3 as well as above pH 3, very low yield biosorption of RBBR was observed. No differences were found between chemically modified and unmodified biomass in terms of RBBR dye biosorption capacity. In the first 15 min, almost 50% RBBR dye was removed from the solution and reached equilibrium within,180 min at pH 2. Biosorption isotherm obeyed Langmuir isotherm model and pseudo-second-order kinetic model.
