Authors: Singh, D K; Garg, S K; Bhardwaj, R K
Abstract: <span style="mso-bidi-language:HI">Triisoamyl phosphate (TIAP) has been synthesised
using isoamyl alcohol and phosphorous pentoxide. The removal of Cr(VI) using TIAP
in benzene has been carried out. The effects of solvent, acid strength,
presence of electrolyte, concentration or metal ion and extractant and contact
time on extraction efficiency
<span style="mso-bidi-language:HI">have been examined. The extracted species is in
the form of 2HCrO<sub>3</sub>CI.3TIAP. Experiment has also been carried out for
the continuous removal of <span style="mso-bidi-font-family:Arial;
mso-bidi-language:HI">Cr(VI) <span style="mso-bidi-language:HI">using
liquid membrane of <span style="mso-bidi-font-family:Arial;mso-bidi-language:

Authors: Kumar, C Siva; Muralidharan, V S; Begum, S Shabanna; Mayanna, S M
Abstract: <span style="mso-bidi-language:HI">Study on the electrochemical behaviour of
non-cyanide zinc complexes received revived interest, as many of the zinc
plating baths employ non-cyanide zinc complexes. Voltammetric studies carried
out on platinum revealed that…

Authors: Sridhari, T R; Dutta, P K
Abstract: <span style="mso-bidi-language:HI">Efficient procedure for the preparation of
maleilated chitosan derivative has been established on the basis of the chemical
modifications. Selective and quantitative maleilation of chitosan proceeds
smoothly <span style="mso-bidi-font-family:Arial;mso-bidi-language:HI">by
<span style="mso-bidi-language:HI">the reaction of chitosan with maleic
anhydride in dimethyl acetamide at <span style="mso-bidi-font-family:
Arial;mso-bidi-language:HI">120 <span style="mso-bidi-language:HI">°C
for <span style="mso-bidi-font-family:Arial;mso-bidi-language:HI">4 <span style="mso-bidi-language:HI">h and resulted in the formation of amide product.
Thereafter imidization by curing was done. The structure of the derivative well
confirmed by titration of carboxylic groups, elemental analysis and IR
spectroscopy. The resulting maleilaied chiosan exhibits much improved swelling
in water. It is expected that multifunctional polar group in chitosan should
have good dye adsorption capacity than pure chitosan.
