With a goal to understand the fate and behavior of chlorinated organic pollutants such as dioxins, chlorine stable isotopes have been paid a great attention. In order to quantify the isotopic compositions of thus organic materials, we preliminarily investigated a supercritical extraction method to obtain chloride from a sample powdered poly-vinyl chloride (PVC), without adding any organic solvent. The experiment was performed at the supercritical condition of water, over 600℃ and 30MPa, resulted that 80％ of the PVC was readily decomposed without occurring a significant isotopic fractionation. This method for the purpose of the Cl isotope analysis of any Cl-bearing organic materials seemed well promising.

In this paper, the technical challenges in enhanced oil recovery using a sodium silicate solution as a multipurpose chemical are introduced to enhance oil recovery by alkaline flooding and prevent channeling flows through high permeability layer/regime and geological storage of carbon dioxide CO 2. We have focused on the sodiummetasilicate-hydrates Na 2 SiO 3 .9H 2 O; S-MS from many types of chemicals. Firstly, oil properties with S-MS solution pH12-13 are presented to carry out alkaline flooding based on measurement results of interfacial tension IFT , contact angle and emulsion formation with oil considering reservoir-water salinity. Secondary, in-situ gel formation using the reaction between S-MS solution and dissolved CO 2 is introduced as a blocking agent in high permeability owpasses in an oil reservoir with different permeability layers. Both of Raman and SEM-EDS spectroscopy revealed that the formed gel is a sodium carbonate type gel SC-gel. Physical characteristics of SC-gel were investigated in respect of S-MS concentration, temperature and CO 2 gas pressure. The blocking effect was evaluated by threshold pressure gradient and gas permeability by forming in-situ SC-gel in a sandstone core. Then the core ooding test using heterogeneous core consists from two sandstones cores with different permeabilities was carried out to nd improvements in oil recovery by alkaline ooding using S-MS solution and blocking effect by the in-situ gel formation with CO 2 gas injected. Furthermore, a new system a kind of Carbon-dioxide capture, utilization and storage using the S-MS solution is proposed for CO 2 capture, usage and geological storage into relatively shallow oil reservoirs or aquifers meet a safe and economical onshore CO 2 sequestration. Furthermore, it is also expected that the in-situ gel formation between S-MS solution and CO 2 gas emitted from res of peat layer or coal seam has a possibility to extinguish large scale res contributing global warming.
