    Abstract: The invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one sulfamic acid or salt thereof to inhibit bacterial adhesion to the submergible surface. The invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one sulfamic acid or salt thereof to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The sulfamic acid used in the method of the invention has the formula R1R2NS(O)2(OH). In this formula, R1 and R2 are independently a hydrogen, a C4- C20 alkyl group or a cyclohexyl group. However, R1 and R2 are not both hydrogen. Alternatively, R1 and R2, together with the N, may also form a 5-8 membered heterocyclic ring having formula (I). In the heterocyclic ring, X is O, NH, or CH2. The salt of sulfamic acid can be an acid salt or quaternized sulfamic acid salt. The present invention also relates to a composition containing sulfamic acids or salts thereof useable in the above methods. The compositions comprise at least one sulfamic acid or salt thereof in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.

    Abstract: Un método para controlar el crecimiento de al menos un hongo sobre un pellejo animal curtido, que comprende la operación de poner el pellejo, antes, durante o después de la curtidura, en contacto con un cianoditiocarbimato de fórmula (I): **(Ver fórmula)** en que: X es un halógeno; R es un grupo alquilo C1-C14 sustituido o no sustituido, un grupo alquenilo C2-C14 sustituido o no sustituido, un grupo alquinilo C2-C14 sustituido o no sustituido, o un grupo sustituido o no sustituido y definido por Y-Ar-(CH2)m- o por Z-(CH 2) n-; Ar es un grupo arilo sustituido o no sustituido y seleccionado entre fenilo y naftilo; Y es H, halógeno, NO2, R 1 , R 1 O, o R 1 R 2 N; Z es NC, R 1 O, R 1 OC(O), o R 1 OCH2CH2(OCH2CH2)p; m varía de 0 a 3; n varía de 0 a 3; p varía de 0 a 3; y R 1 y R 2 son independientemente H o alquilo C 1-C 5 sustituido o no sustituido; en una cantidad eficaz para controlar el crecimiento de al menos un hongo sobre el pellejo curtido.

    Abstract: The invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one amino methyl phosphonic acid or salt thereof to inhibit bacterial adhesion to the submergible surface. The invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one amino methyl phosphonic acid or salt thereof to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The amino methyl phosphonic acid used in the methods of the invention has the formula R1R2NCH2P(O)(OH)2. In this formula, R1 and R2 are independently a C6-C20 alkyl group or a CH2P(O)(OH)2 group. However, R1 and R2 are not both a CH2 P(O)(OH)2 group. Alternatively, R1 and R2, together with the N, may also form a 5-8 membered heterocyclic ring having formula (a). In the heterocyclic ring, X is O, NH, or CH2. The salt of an amino methyl phosphonic acid can be an acid salt or a quaternized amino methyl phosphonic acid salt. The invention also relates to a composition containing amino meth yl phosphonic acids or salts thereof and useable in the above methods. The compositions comprise at least one amino methyl phosphonic acid or salt thereof in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.

    Abstract: A method for controlling the chemical treatment of a solution comprises the steps of feeding a treatment chemical into the solution, applying an external voltage across a reference electrode and a working electrode of a voltammetric sensor while the electrodes are immersed in the solution, measuring a current that flows through the working electrode, converting the measured current into a feedback signal indicative of the concentration of treatment chemical in the solution, and using the feedback signal to control the rate of feeding the treatment chemical.
