    摘要： The present invention relates to a composite material with an improved structure in which is dispersed an active organic compound, and a method for treating effluents, in particular a method for treating photographic effluents. The present invention relates to a composite material that takes the form of a structured gel comprising an aluminosilicate polymer matrix in the form of fibers in which at least two distinct fibers are interconnected by at least two covalent bonds to form an irreversible chemical gel and, dispersed in the matrix, an active organic compound. The choice of the degree of cross-linking of the matrix makes it possible to control the diffusion of a hydrophilic active organic compound. The invention further concerns a method for preparing such a composite material.

    摘要： The present invention relates to a composite material in which an active organic compound is dispersed, as well as to an effluent treatment process, especially a photographic effluent treatment process. The composite material comprises an aluminosilicate organic-inorganic polymer matrix in fiber form comprising at least on the surface an organic radical having a —SH or —S(—CH2)n—S— function with n between 0 and 4 and in which an active organic compound is dispersed.

    摘要： A process for monitoring the electrolyte circulation in an electrolysis cell, in which an electrolyte flow generated by a circulation pump is generated between the electrodes of the electrolysis cell and the electrolysis is performed by a constant electrolysis current or electrode potential. The process includes the steps of setting at least three different electrolysis states in the cell by a switching on and off of the circulation pump and the electrolysis current or the voltage at predetermined times; performing multiple measurements of at least one electrolysis parameter in a predetermined period of time and forming a mean value of the measured electrolyte parameter for each of the three electrolysis states; forming of a first gradient ST1 from the mean values of the electrolysis parameters of the first and second electrolysis states and forming a second gradient ST2 from the mean values of the electrolysis parameters of the second and third electrolysis states; and comparing the gradient ST1 with the absolute value of the gradient ST2, where a greatly reduced electrolyte circulation applies with ST1

    摘要： A process for the processing of spent photographic baths of black and white processes, namely developing baths with a preponderant content of alkali sulphite, particularly sodium sulphite, and fixing baths with a preponderant content of thiosulphates, particularly ammonium thiosulphate and/or sodium thiosulphate is proposed and is characterized in that following the deposition of the silver contained in the baths, the spent fixing baths are brought to a pH of approximately 0.5 with concentrated HCl and the elementary sulphur resulting from the decomposition of the thiosulphates is separated, whilst the remaining sulphurous acid intermediate solution is mixed with the spent developing baths and adjusted to a pH of approximately 2 and the resulting, SO.sub.2 -supersaturated solution is heated and pure SO.sub.2 is drawn off in a vacuum. Finally, the residual solution is adjusted to a pH of approximately 10 with Ca(OH).sub.2 and the liberated ammonia is drawn off.

    摘要翻译： 提出了一种处理黑色和白色工艺用过的照相浴的方法，即开发具有碱金属亚硫酸盐，特别是亚硫酸钠的主要含量的洗浴，以及含硫代硫酸盐，特别是硫代硫酸钠和/或硫代硫酸钠的重要含量的固定浴。 并且其特征在于，在沉积包含在浴中的银之后，用浓HCl将废定影液的pH调至约为0.5，并且由硫代硫酸盐分解产生的元素硫被分离，而其余的亚硫酸 将中间溶液与废显影浴混合并调节至约2的pH，并且将所得的SO 2过饱和溶液加热并在真空中抽出纯的SO 2。 最后，用Ca（OH）2将残余溶液调节至约10左右，释放出的氨被排出。
