b-CD) cavity protons as well as roxatidine acetate hydrochloride aromatic ring protons revealed the formation of a RAH–b-CD inclusion complex. Detailed FTIR and NMR spectroscopic (1H NMR‚ COSY‚ NOESY‚ ROESY) studies have been done. The stoichiometry of the complex was determined to be 1:1‚ and the overall binding constant was also determined by Scott’s method. The NOESY spectrum confirmed the selective penetration of the aromatic ring of RAH into the b-CD cavity in comparison to that of the piperidine

The results of the 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]

In this experiment‚ an aromatic carboxylic acids namely benzoic acid will be prepared by oxidizing benzyl alcohol which is a primary alcohol. The oxidizing agent used is alkaline potassium permanganate (VII). Benzyl alcohol is an aromatic alcohol with the formula C6H5CH2OH. It is a primary alcohol because the carbon atom which the hydroxyl group‚-OH group is connected joins to one
