摘要:
An alginate gel adsorbent to remove heavy metal ions according to the present invention is prepared by adding dropwisely 0.1-5 wt % alginate solution to a polyvalent cationic solution thereby cross-linking alginic acid with polyvalent cations. An alginate gel adsorbent containing activated carbon capable of simultaneously removing heavy metal ions and organotoxic materials, that is, activated carbon/alginate gel adsorbent, is prepared by adding dropwisely a mixed solution of 0.17-10 wt % of alginate and 0.1-10 wt % of activated carbon powder to a polyvalent cationic solution thereby cross-linking alginic acid with polyvalent cations in order to immobilize polyvalent cation to alginic acid containing activated carbon. The polyvalent cationic solution is selected from the group consisting of calcium chloride (CaCl2), strontium chloride (SrCl2), barium chloride (BaCl2) and aluminium chloride (AlCl3). A flat board or a thin membrane coated alginate gel adsorbent can be prepared by coating alginate gels onto a supporter such as paper, wood plate and textile fabrics. The alginate gel adsorbent for water purification can be applied to a water purifier as well as a process of wastewater treatment. The alginate gel coated onto a supporter is prepared by immersing a supporter in 0.05-5 wt % alginate solution so that the supporter may uniformly adsorb the alginate solution, immersing the supporter in a polyvalent cationic solution thereby forming alginate gel on the surface of the supporter, and drying the supporter formed with alginate gel thereon.

An epoxy resin composition having an epoxy resin, a curing agent, and inorganic filler as main components is provided. The epoxy resin includes an epoxy resin of Chemical Formula. Accordingly, the thermal conductivity of the epoxy resin composition can be increased because the epoxy resin has a mesogen structure that facilitates crystallizability. In addition, a high radiant heat board can be provided by using the above-mentioned epoxy resin as an insulating material for a printed circuit board.

The present invention relates to a method for analyzing genes using SDL-PCR (separation of displaced ligation probe-based PCR), and more particularly to a method for analyzing genes using SDL-PCR, in which probes comprising a nucleotide sequence complementary to the gene of interest are ligated with each other by ligase, and another probe capable of hybridizing to the probes is hybridized and extended, thereby preparing a template probe, and the template probe for the gene of interest is amplified using universal primers.According to the SDL-PCR method of the present invention, non-specific amplification can be minimized by removing non-ligated probes or genomic DNA using a tag, and separation can be achieved within a shorter time compared to a separation method that is performed using exonuclease. In addition, ligation, separation and polymerase chain reaction processes can be performed in a single solution in a single tube, and thus a plurality of genes can be amplified at the same time in an accurate and rapid manner.
