POTASSIUM DETERMINATION BY THE COBALTINITRITE METHOD AS AFFECTED BY TEMPERATURE AND pH.
Rapid chemical analysis of plant and soil extracts for plant nutrients is beingv given widespread attentioii. Potassium is one of the most important and expensive planit nutrienits and requires, therefore, special coiisideration of methods employed for determining, its coneentrations in soils and plant tissues. The cobaltiniitrite iimetlhod for potassiumi deteriliinations in extracts of soils a...
متن کاملColorimetric determination of potassium by Folin-Ciocalteu phenol reagent.
A method for the colorimetric estimation of manganese by reduction of the phosphomolybdicphosphotungstic acid phenol reagent has been described (Abul-Fadl, 1948). Cobalt was also found to give a similar colour reaction in the presence (but not in the absence) of amino-acids. Conversion of cobalt into the cobaltinitrite did not affect its response to this reaction. As methods for the estimation ...
متن کاملPotassium-sensitive G-quadruplex DNA for sensitive visible potassium detection.
A novel visual method for K(+) detection is developed utilizing a K(+)-sensitive G-quadruplex DNA named PS5.M as the sensing element. In the absence of K(+), PS5.M is in a random coil state and does not bind hemin. Upon addition of K(+), PS5.M folds into the quadruplex structure stabilized by K(+). Such quadruplex structure is able to bind hemin to form the hemin-G-quadruplex DNAzyme that catal...
متن کاملQualitative obstacle detection
Three diierent algorithms for qualitative obstacle detection are presented in this paper. Each one is based on diierent assumptions. The rst two algorithms are aimed at yes/no obstacle detection without indicating which points are obstacles. They have the advantage of fast determination of the existence of obstacles in a scene based on the solvability of a linear system. The rst algorithm uses ...
