✦ Synopsis

Tribenuron-methyl a sulfonylurea herbicide, readily photodegraded in aqueous solution under sunlight and UV light. The photoproducts identiΓΌed were N-methyl-4-methoxy-6-methyl-1,3,5triazine-2-amine, methyl 2-(aminosulfonyl) benzoate, o-benzoic sulΓΌmide, N-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)-N-methyl urea and N-(2-carbomethoxyphenyl)-N-(4-methoxy-6-methyl-1,3,5triazin-2-yl)-NΒΊ-methyl urea. The rate of photodegradation of tribenuron-methyl in diΓΎ erent types of water followed ΓΌrst-order kinetics with signiΓΌcant correlation coefficient, increased with increase in pH and was also dependent upon the dissolved impurities.

Inorganic germanium(I1) in micromolar concentrations was reacted with methyl iodide (CH3J) and methylcobalamin (CHJ-CoB,,) at various pH values and with different salt matrices. In all experiments monomethylgermanium was the only product. The reaction with CH,-CoB,, at pH1 yielded approximately 1.3%

In this study we examine the potential for using brushite (dicalcium phosphate dihydrate) as a coating for orthopedic implants. It was found that brushite is transformed into a more stable calcium phosphate (hydroxyapatite), regardless of the aqueous transforming media utilized. The transformation w
