experiments carriedout for the degradation of fabric dyes from aqueous solution using Chara and Chara beads are discussed below.Various analytical techniques like UV-Vis‚ FTIR spectroscopy were used to confirm the decolorization as UV-Vis spectroscopy; FT-IR spectroscopy and toxicity bioassay were truly used [14]. Also‚ Fourier transform infrared spectroscopy (FT-IR) is widely used to confirm the product obtained after decolorization of dye degradation experiments [15]. It helps in determination
