The Effect of Wavelength and pH on the Direct Photolysis of Chlorophenols by Ultraviolet Excilamps

The protective effect of 4-NC and a -tocopherol on oxidative stress in egg PC vesicles and erythrocyte ghost membranes initiated by AAPH or FeSO 4 +H 2 O 2 was evaluated using the

The influence of both pH (2, 4, 6, 8 and 10) and initial anion concentration on sulphate uptake was studied by placing 1 mL of hydrated resin in contact with 100 mL of sodium
