Enhanced electrocatalytic oxidation of isoniazid at electrochemically modified rhodium electrode for biological and pharmaceutical analysis.

By designing a novel electrolytic flow cell, the strong oxidant BrO– was electrogenerated on-line in KBr solution and its concentration could be readily adjusted on-line with the flow-injection technique and an electrochemical method. The chemical reaction between BrO– and luminol in alkaline medium is accompanied by weak emission of light due to chemiluminescence (CL). It was found that the isoniazid can greatly enhance this weak CL intensity when present in the luminol solution. Based on this observation, a new flow-injection CL method for the determination of isoniazid had been proposed in this paper. The detection limit was 7.0 × 10–9 g ml–1 isoniazid and the CL emission intensity was correlated with the isoniazid concentration in the range 2.0 × 10–8–1.0 × 10–6 g ml–1 with an RSD of <5% (n = 7). The system was applied successfully to the determination of isoniazid in pharmaceutical preparations and the possible CL mechanism is discussed.

Capillary electrophoresis (CE)/electrochemical detection (EC) for the simultaneous determination of hydrazine and isoniazid has been developed The electrochemical method uses a novel modified electrode dispersed with ultrafine platinum particles on the surface of a 30 mu m carbon fiber microelectrode The unique characteristic of the Pt-particles modified carbon fiber microelectrode is its excellent stability The current measurement for hydrazine is more sensitive than that of isoniazid Selective determination of trace amount of free hydrazine in isoniazid and its formulation can be achieved at applied potential of 05 V

Most of the fuzzy classifiers are created by fuzzy rules based on apriori knowledge and expert's knowledge, but in many applications, it's difficult to obtain fuzzy rules without apriori knowledge of the data. To solve this problem, a new way of creating Mamdani fuzzy classifier based on Mamdani fuzzy logical system is proposesed in this paper, and the new fuzzy classifier is improved with the genetic algorithm further. The result of data simulation with Iris data shows the new Mamdani fuzzy classifier has minimum number of features, minimum number of fuzzy rules and better precision.

It is difficult for basic genetic algorithm and evolutionary programming algorithm to converge at global optimal solution of real-continual function in practice, although both of the algorithms have the ability for getting the global optimal solution with convergent probabilities 1 in theory. In this paper, a new hybrid genetic algorithm based on clan competition is proposed, and it is proved that the probability of the new algorithm convegent to the global optimal solution is 1, Numerical experiments results illustrate that, compared with the former two algorithms, the new algorithm is the robustest among the three algorithms, what's more, it has the highest precision with the equal parameters.
