“…As shown in Figure 1d, the decolorization efficiency increased with rising temperatures. These findings are compatible with those reported by Çetinkaya Dönmez et al (1999) and Daneshvar et al (2007). It could be due to the reduction of plant membrane permeability and, consequently, the reduction of water absorption and water-soluble molecules in low temperatures (Vafaei et al, 2013).…”

Phytoremediation is a low-cost and effective technology that removes pollutants, such as dye-containing effluents, from the environment through the use of plants. In the present study, the potential of Lemna minor L. for decolorization and degradation of the triarylmethane dye malachite green was investigated. The results revealed that the decolorization ability of the plant species is as high as 88%. The effect of some operational parameters (initial dye concentration, temperature, pH, and amount (weight) of plant) on the efficiency of biological decolorization process was determined. The metabolic fate of the dye was proposed by identifying 8 intermediate compounds produced during this process by gas chromatography-mass spectrometry. Some physiological responses of the plant were evaluated under 10 and 20 mg/L of the dye, with notable increases in superoxide dismutase and peroxidase activities at high concentrations. The results suggested that dye treatment induced oxidative stress and demonstrated duckweed's capacity to upregulate its antioxidative defense.

“…Daneshvar et al [58] investigated the effectiveness of biological decolorization of synthetic dye solution containing malachite green. Batch experiments were carried out at different initial dye concentrations (2.5-12.5 ppm), temperatures (5-35 •C) and pH values (2.5-10) using various types of algae (Cosmarium, Chlorella, Chlamydomonas and Euglena).…”

Most of the textile dye removal techniques operate within temperature and pH ranges of 20-60 °C and 2-12, respectively. Both the pH and temperature have been reported to have significant effects on the efficiencies of the dye removal techniques. In this study, the effects of pH and temperature on the stability and color measurement (absorbance) of the textile dye remazol brilliant at different dye concentrations were investigated. Changing the pH from 1 to 13 and /or the temperature from 15 to 55 °C did not have any significant effect on the absorbance of the dye remazol brilliant blue at two concentrations (65 and 300 mg L¯1). The results showed the stability of the remazol brilliant blue in water under wide ranges of temperature and pH. However, the neutral compound C 22 H 16 N 2 Na 2 O 11 S 3 is transformed to an ionic form with either negative charge [C 22 + under acidic condition. The formation of ionic form of the dye will facilitate its removal by various removal techniques. The results showed that a standard curve can be constructed at ambient conditions (a pH of 7 and a temperature of 25 °C) and used to determine the concentration of the dye using the colorimetric method.

“…Therefore, the Taguchi approach is used in many domains such as environmental sciences [36,37], agricultural sciences [38], physics [39], statistics [40], management and business [41], medicine [42] and in chemical processes as well [43]. Here, some of the literature reviews are given, which clearly show the application of Taguchi method in the chemical processes of various industries.…”

Design of experiment is the method, which is used at a very large scale to study the experimentations of industrial processes. It is a statically approach where we develop the mathematical models through experimental trial runs to predict the possible output on the basis of the given input data or parameters. The aim of this chapter is to stimulate the engineering community to apply Taguchi technique to experimentation, the design of experiments, and to tackle quality problems in industrial chemical processes that they deal with. Based on years of research and applications, Dr. G. Taguchi has standardized the methods for each of these DOE application steps. Thus, DOE using Taguchi approach has become a much more attractive tool to practicing engineers and scientists.And since the last four decades, there were limitations when conventional experimental design techniques were applied to industrial experimentation. And Taguchi, also known as orthogonal array design, adds a new dimension to conventional experimental design. Taguchi method is a broadly accepted method of DOE, which has proven in producing high-quality products at subsequently low cost.
